I was on the phone for over four hours in an attempt to resolve a ten minute issue. I am new to AT&T and never have I experienced such demonic, rude, and disrespectful customer service. I am very shocked! I am so upset to the point where I am just tired. The first time I called in, I spoke with a rep named Justin. I explained to him two charges that I received that were not valid. I also asked him for a breakdown of this month's bill. His tone was very high and he was very rude with his responses to me while cutting me off. I asked him for his job ID along with the number to corporate. He gave me his job ID and told me to hold on, I agreed and 20 seconds later; I heard the dail tone. Justin hung up in my face. I thought to myself, "wow" because I've worked for a call center and I would have gotten fired on the spot if I were to speak with a customer within that manner. I called back and spoke with John. He listened to the issues I was having and tried to help. He stated that because the credit was too big, he would have to transfer me over to his supervisor. I agreed and he placed me on hold. I was transfered to Abigail whom I explained my issues to. I told here that I was charged 2.00 for a return call fee (in which I did not make) and that I was told that the wireless modem would be free if I were to sign up for the DSL 6.0 package. I informed her that there was a charge for the modem on this month's bill in error. Abigail researched the notes on my account to make sure that the information I was giving was valid. I also gave her Justin's ID and the job ID to the individual who told me that the modem would be free. Abigail verified the notes and issued me the easy credit of 12.00. I told her that I would make the payment online. I went online to register and make a payment but to my surprise I was unable to retrieve a registration code. I called tech support. They tried to retrieve it, but it did not work. I was then told by Sam within tech support that she would proccess the payment for me and have the registration code mailed to me within 3 to 5 business days so that my payment would not be late. I agreed and took out my card to pay. I was told that the balance was $59.250 which was incorrect due to the $12.00 credit. Sam stated that because she was in tech support, she was unable to see the credits and would be more than happy to transfer me over to billing. I agreed and waited to be transfered. I was transfered over to Marcel. I explained to him that I was issued a credit in the amount of $12.00. He stated that there were no credits and no notes within the system reflecting anything about it. I asked him for his job ID and he sated that because he works within retention; he does not have an ID. He also stated, "Do I have to tell you twice for you to get it? There are no notes within the system about any of this. What part of that did you not understand?" For a minute I thought this was a spoof or I were being punked. I then told him that as a customer service representative, you do not have the right to  talk to the consumer who generates your paycheck within that manner. I told him that I was very sad to witness his behavior towards me and would like to speak with a supervisor. He stated that there are no supervisors within his department. I assured him that it is against the FCC Rules and Regulations for me NOT to speak with a supervisor. He then stated that they are busy and to call back later.  I then asked him for the number to the corporate office and he began to raise his voice at me and for 30 seconds refused to give it to me. I asked him what was his supervisor's name and he said that he had many. I told him to give me there names and he started yelling out names random. I told him that because of his rude behavior I have file a complaint against him, he stated "GOOD LUCK WITH THAT!" I then asked him again for his supervisor, he said no and I stated that I would hold. Two minutes after that he hung up. He is based in South Carolina. I am extremely shocked that AT&T allows such garbage to work at their company. There are millions of Americans who are out of work waiting for a job with AT&T. This young man was blessed with this great job and decideds to behave like this??? I can't believe it! This is who you hire over individuals who know how to put the customers first? This is truly sad. I called back and asked to speak with a Supervisor. I transfered over and explained to the supervisor named Ebwarg. He told me that the information was within the system, notes and everything and apologized for the issues I were having. I asked him if I could file a complaint against Marcel for giving me an invalid number to corporate and for his ridiculous behavior while on the phone with me. He wrote down my complaint and I told him that I was also going to file a complaint against Marcel with the FCC because his rude customer service was THAT EXTREME. For years I thought about buying service each month from AT&T and when I finally do, this is the level of service I receive? How is it possible to be number one when the customer service level is 0? If anyone has the number to corporate; please post it. I am going to put an end to this so that more qualified individuals can represent the company. AT&T please stop outsourcing your calls to independent call centers (i.e. Sitel, Alorica). These individuals are underpaid and they do not have quality customer service when dealing with your customers.
