Constantly Overcharged/Billing Issues Every Month

For the past 4 months my bill keeps going up along with added promotions that I never asked for or they're offered to me and I decline and miraculously they appear on my bill. Each month I call to dispute my bill 4 months. I have been calling them. Spoke with them today. Today I had a voice box x2 added to my account I had to look up what that was. I never asked for that. I deem this to be fraud. I told them I was going to report them to the consumer protection bureau 

When my bill came in I was afraid to read it because I knew what was going to happen. I It raises my blood pressure each time I see my bill is supposed to be $129. When I looked at it this morning it was 183. I have a diamond membership It's wrong what they do. The gentleman told me he was going to fix it. Tell me within 24 hours the amount on the app would change. I'll look tomorrow to see if it's changed. More than likely it won't. I'm sick of dealing with Xfinity each month. I'm sick of them trying to get money out of me that is not owed to them
