$100 tech visit on top of having internet that wasn’t working for a whole month? Didn’t even request a credit for the unreliable internet.

I’ve contacted Xfinity through the virtual agent support many times and have been promised that a $100 credit for a $100 charge would be applied. They’ve said 24-48 hours and it will reflect on my bill 48 hours will pass and of course! Nothing changes. Same with a credit for the Nightmare of a month of November where I received no help and spent way too much time trying to fix myself. I still wasn’t able to receive any help with fixing my initial problem and have tried to be as patient and kind as possible. It’s crazy when you’ve been promised credits within 24-48 hours so many times just for nothing to happen. I feel I’ve been treated horribly and lied to so many times, it would be a joke to call this customer service. I finally was able to get ahold of someone just for them to make more promises and have me wait for 30+ minutes saying they promise it’ll be reflected on my bill, Just to HANG UP on me and lie for the 4th time. Is there anyone from Xfinity customer support that will be true to their word? Or should I continue to expect to get lies? This is extremely frustrating and I don’t feel as a customer I should even come close to be feeling this way about a service I pay for? In a nut shell I didn’t have reliable service for a month, then because I asked for assistance they charged me $100 on top of it all already initially pouring hours into trying to solve things myself. Next I’ve been lied to multiple times with empty promises and abandoned and hung up on multiple times. This has been the worst experience I’ve had with any internet service provider. It almost feels like a joke calling it a “service provider” when you’ve been lied to as many times as I have with lack of any support. Can anyone help me with this?
