Yes, in my case was Verizon. On April, we decided to cut the cord, contact them via CHAT, mind you because phone calls were not working. Told them to take out my land line and my TV just to leave us with the Internet, and that we wanted to upgrade the Internet to 1 GB, which is their best one. First they said yes that they need it to send a technician to upgrade their cables to be able to use the new Internet, and to wait for them to contact us. I contact back 2 weeks later and asked them if they had cut off my request, they said we had to wait for the Technician (that due to COVID they did not now when he will be coming) so we asked them to cut off anyways, so they did 2 separate requests so we would it be paying for the TV while we waited, so we went to their store and returned the boxes, and waited, and waited for them to come for the upgrade, scheduled 2 times and suddenly canceled us twice no explanation. My neighbor had her technician come to her house in 3 days here we were 2 months later and nothing, so we called and they said "It is our system somehow they do not allows to set an appointment FOR YOUR ACCOUNT until DECEMBER!! What? had a supervisor create a NEW Ticket order and the then got an appointment for July 20th, then suddenly we had 2 appointment 1 for the 20th and 1 for the 16th, 3 months later the Technician came and upgrade it. but the Customer Service was horrible (1 lady told us that we were Stupid and just had to wait and hang up on us), and they blamed everything on COVID. Also could not use their app because of the same thing, until DECEMBER when they could come then it would work. Finally everythng is good but it has been a nightmare.
If we had a better company around here I would have changed but honestly Verizon is the best in my area
