My account is totally messed up [Edit]

On June the 6th I called Comcast and talk to a gentleman named Arat and explain to him that I wanted to renew my contract and lower my bill if possible but I didn't want to lose any of the things that I have. He assured me he could help me and that he had a new promotion for 1100 MB for 60 months and nothing would change on what I had already. He sent me a contract and I agreed to the terms but then notice later that it did not say anything about Xfinity Voice. So I called back a couple of days later and talk to a gentleman named Adam and he assured me that I still had Xfinity Voice Even though it didn't say that on the agreement and he could get me a better rate. So he sent me the terms and I signed it and then notice that he had lowered my speeds to 400 MB and cancel my Peacock which I supposedly get because I am a diamond member of 36 years. So again I call back and I talked to a gentleman and he told me that my Peacock was canceled because I didn't have 1100 MB plan. I tried to explain to him that I had gotten it free because I was a diamond member but anytime we that all he could do was escalate it to the promotions Department. I have been told this before and then never heard from anyone. The last time I had a problem I posted it on this forum and the customer service rep for Xfinity solved my problem quickly. I am hoping that you are still out there and you can help me with my problem.
