Atnt has the worst customer service in customer service history

I have never met such challenging people untill i decided to try atnt , i made one appointment and the technician showed up to do nothing which caused me to reschedule my appointment two weeks later i called to complain about the lack of service for two hours where i got lucky to get my appointment pushed to a earlier date from 8am - 11am due to me almost cancelling the contract, the second appointment day arrived to find out no tech is showing up, i called to complain and the representative said there is. No sign of a appointment made for that day and was promised a second attempt that same day from 1pm-3pm now i called out of work to wait and find out THAT STILL NO TECHNICIAN SHOWED UP AND AGAIN I CALLED TO COMPLAIN, now i have no option but to reschedule a appointment for a whole nother week later because they do not have anything sooner to service me or cut me a break, the entire atnt team does not care about their actions or their lack of service , note: that all this is just for me to GET SERVICE INSTALLED as a new customer and its the worst experience i had ever , if my apartment complex wasnt contracted with atnt i would go straight back to spectrum, i never had this issue or such complex communication  with spectrum as i do with atnt, i complain to supervisor rolando which i dont find a reason why he is worse then the customer service itself, my apartment complex is gonna hear from me and i will be sure to get them to cancel their contract so i can use spectrum again, atnt truley suks and i prey that nobody uses atnt and their horrible nonsupport team service
