Best telecommunications service provider in Mayfield Heights, Ohio (OH) 2024

Came to this location to have 4 lines transferred over from Verizon. Dom was good initially, but when I received my bill I had charges that I did not authorize. Also, was not told that there would be a charge for next up on the new phones I purchased. I've had to call AT&T customer service 3 times so far with being on the phone for an hour to still have only partial of my bill corrected. Not to mention, I still have to call back again when the next billing cycle starts to have the remaining charges removed that I have to pay for upfront. ~Lisamonea
