Absolute HORRIBLE treatment and customer service

I’ve been with Xfinity for over 10 yrs and have been moderately satisfied with their service (not counting the awful hold times and call lengths!) until recently Ive been having the worst experiences with their customer service that I’ve ever experienced before in my entire life with any service ever! I can’t even believe how awful it’s been! I’ve had to call three separate times with different issues and each call has been over 2 hours!!! I had some issues with the app telling me a certain price and the bill being different which wasn’t fixed after the long call, when they told me it had been. They lied and told me my modem was bad so I opted to rent theirs. Come to find out that was a complete lie after speaking with our Best Buy tech guru. I had to call again to try and get the monthly payment fixed and was told of a bundle promo with mobile xfinity with the rep reassuring me of its authenticity and her telling me the approximate price per month for each service. After a few weeks I was being billed for a lot more than she quoted me previously and realized she didn’t give me a free phone option. She made me believe the monthly price quoted was for the mobile billing when it ended up being the price of the phone! I called again to cancel mobile, return phone and stop the auto pay due to being lied to. After spending at least two hours on the phone he said he canceled my mobile, put in all as fraud and it was going to be looked at, was supposed to get email for Mobile phone return…never received. He told me he made sure the amount to be taken out of my account was placed on a hold until the fraud had been researched. I got a fraud ticket # from him.  After all this… NONE of it was done!! 

I went into the xfinity store to return modem and they couldn’t even help me!

im not sure where to turn. If I call I’m on hold forever and retelling each person the situation and then they saying they fixed it when nothing ends up being done. I do NOT understand what is going on at all. 
I’ve learned to talk to the loyalty department from past experience and this time this hasn’t even worked. This is where I was lied about a bundle deal!
in the meantime I’ll be charged for the mobile bill when I haven’t even used the phone or any of the data or anything due to being lied to. I can see they all work on commission and lie and don’t care how they treat people. If u r going to use xfinity which i recommend not doing!, Make sure u read the fine print with everything u sign and get email confirmations without ending the phone calls! Sounds crazy but this has been a huge mental roller coaster. I cannot even believe how bad I’ve been taken advantage of without any care at all.
