Account change

In October 2022 I started my new service with cable internet and home phone my bill was 185.00  In late October I received a deal if I was to add another service I would receive an additional 40.00 discount so I added to 10.00 camera service.  I took screen shots of the deal, I contacted xfinity to make sure of the deal.  If my bill was 185 then add 10.00 service with the 40 discount I should be at 165.00 EVEN IF I DIDNT GET THE DISCOUNT MY BILL SHOULD HAVE GONE UP TO 195.00 right no! I didn’t get my discount I’m still paying for self cameras no one has ever been able to help me connect them.  I’ve called 100 times spoke to every person some say they saw the discount some say they didn’t and I would go to the store to show them I went to the store. East Boston manage came over said he was busy he would call me and never did. I can’t believe how many times one can get the run around, it’s not fair then I found it I did the chat through messenger I could copy and paste the discount they said they would have someone call me and never did. Then I said never mind put my bill back to where it was and they said no.  Ive contacted the BBB and the attorney generals office.  I’ve been paying monthly 230.00 for services that were 185.00 added a 10.00 camera it shouldn’t be more then 195 without discount with discount it was 165.00 no one will help me! No one wants to do anything. I’ve spoken to a Jessica before who was amazing to work with and I can not seem to find her number. Please can someone help me!
