Nightmare on El Camino Real

I walked into an AT&T store asking for help and, in my work clothes and did not look completely presentable the employees at the AT&T store did not help me, I asked for help with my service being suspended one of the young men there This day I still don’t know his name, asked me if I paid my bill  I told him no, but I had a payment arrangement Because I think AT&T suspending make account prematurely. He then looked at me and said we don’t handle payment arrangements here.  I then asked if I could use the phone to contact ATT, he pointed to a display phone and said to use that. Anyone who has called AT&T knows that it takes quite some time to get in contact with any live person in customer service. What I was not aware of is the display phones only allow 5 mins of call time then it drops the call, this rep was aware of this. As I was explaining to the agent after the third dropped call what my intent was I realized I should tell her I was a business customer with more than one line. I will not bore anybody with the rest of the story even though there are parts that really really devastated me as a business owner I am just writing on this form because this is my only way of trying to see how can I get in touch with somebody at AT&T management to help me resolve this matter being that they have no chatline or anything like that I am looking to close my account immediately and this is not a hyperbole this is not a joke I am just not gonna give out account information on this forum but if any AT&T management is monitoring I am a real business customer looking to have a real situation resolved and you’re more than welcome to privately communicate with me if you know anything about the situation
