unacceptable

I wanted to start this email by saying I am extremely disappointed with the service and care of my situation as a loyal customer and a disabled veteran of the U.S Air Force with 1,000+ combat hours. I don't know if this is a normal way to deal with customers but it is completely unacceptable! Since December of 2024 i have been having an issue, so first the service in my area was upgraded to 2 gigs which overloaded my store bought modem and router. After a week of going back and forth between netgear and xfinity pointing fingers it was finally admitted that this was the problem. So long story short I'm talking with the agent and he gives me a "deal" because I was told that the wifi speed I had was unavailable. I accept the deal of paying $88 dollars a month for the wifi bill.Then the agent offered me another deal where if i open a mobile line i can get the second line free, with and $100 rebate per line for bringing a qualified phone and it was supposed to $40 off my wifi bill. So I left T-Mobile, whom I've been a customer for 10+ years trusting Xfinity. Called after a few months of my mobile being $80 and not receiving the rebate or $40 off the wifi bill and was told that it takes time and should be on the next bill. I also switched to the xfinity modem since I couldn't use the store bought modem and router anymore. Once I switched the modem the wifi started to have issues still and i had a tech come but they couldn't find anything. So I tend to just deal with the issue until maybe a few months later where I notice I was getting DOUBLE charged out of my account from xfinity. Since I have it on autopay I didn't notice, but somehow the tech that gave me the deal opened up a seperate account under the same address and left the other account open. So I was getting charged $88 and $120+ for wifi under the same address. I go into the store and they help me, which i appreciate and close out the account and issue a refund. But now once customer service closed the account for the wifi they left the mobile open, so i have an account open for mobile and wifi. Now I'm over paying for wifi because they closed the account where I was paying $88 and now I'm paying $136. My mobile bill is $88 if i'm not mistaken because there is no wifi on the account which they say xfinity has fees for. So I called the mobile customer service and the agent I got was good. He got straight to the point, my bill is $37 .Now my wifi is the problem. I call them and they tell me the promotion I had is gone, which I stated isn't my fault. Why do i have to pay extra for your (xfinity) mistakes. So I was told the best they can do is $120 and $110 with auto pay which I stated is unacceptable. Also while going through this I am extremely respectful keeping my bearings. I just gave in and said I will decide to talk to someone else. The person I  then spoke to was an xfinity assistant and it was initially for my continuously bad wifi connection, but the agent offered an ok deal. The deal was wifi ,now tv,and an ipad for $95 dollars monthly and a 5 year price lock. So I took the deal already suspicious because of the last issue so I made sure I downloaded the transcript and took screenshots just in case. And of course there is an issue, the agent said adding the wifi and  now tv and to come back in 4-5 hours. Came back later that night and the agent I got did not recognize the deal then said they did and put the order in. But insisted on adding a tech in the chat to explain how to use now tv, but once the agent joined he was not fully informed on the situation and said that he couldn't see the order the last agent put in. The agent tried to give me a deal but it wasn't the same so I insisted on speaking to someone on the phone. And still the agent on the phone said they never heard or seen that deal and that it was not a 5 year price lock just a year. I will attach the entire transcript. I just want to say I am extremely tired of this company, the customer service and the overpaying constantly monthly and then being promised something twice and never receiving it. There is no accountability with the company. These agents can just say and do anything to get the customer off the phone and the customer is stuck dealing with the headache and having to double check the work of this company. This is completely absurd. EIGHT MONTHS later I still have not received the two $100 rebates, the $40 dollars off the wifi bill or proper price for wifi; this is INSANE!
