Deceptive selling practices and the lacks ownership and accountability of their mistakes

In February I called Xfinity looking for promotions to reduce my every growing monthly bill. I was offered a "special promotion" that reduced my bill by about $25. It included all my existing services, an increase in Internet speed, a better version of Peacock, a free new iPhone 17, and a 2-year free trial of their mobile service. What I actual got was the following headaches which I reported to the FCC. 

1. Told no change in service and save $25 on a special promotion. False. Netflix access issues. 
2. Told I should have Netflix and to call Netflix to get it resolved. False. Netflix informed me that the issue was with Xfinity Comcast. 
3. Told they corrected the issue and try again later. False. Tried later and still had access issues.
4. Told again they corrected the issue and try again later. False. Tried later and still had access issues. 
5. Told again they corrected the issue and try again later. False. Tried later and still had access issues. 
6. Told quickest way to resolve the issue would be to re-add Netflix but it would have no impact to my bill. False. Monthly bill increased.
7. Told I would receive a "free" new iPhone 17. False. Received an older Motorola Android phone.
8. Told I would only have to paid the tax on the new "free" phone. False. Later discovered they were billing me for the phone. 
9. Told the "special promotion" to reduce to my cable bill was associated with the trial offer of a free phone and plan for two years. False. Later told that my cable plan and phone plan were not tied together. This was the only reason why I accepted the promotion and the reason why I cancelled the phone plan. My goal was to reduce my cable bill without losing any existing services.  
10. Told I could cancel the free trial phone plan at any time. False. Later told I needed to cancel it before the end of the first 2 weeks which was actually before seeing my monthly bill and the charge for the new phone.
11. Told I could return the phone to the local Xfinity Comcast store. False. The store refused to take the phone and was instructed that it had to be done by calling Xfinity Comcast.
12. Told the local Xfinity Comcast store was incorrect and to return it to the store. Told I would not have problems with the store because they included all the information in the system notes. False. Store refused to take the "free" phone and said there were no notes on file indicating such. 
13. Told monthly bill was incorrect, applied a $25 credit, and told it would be fixed going forward. False. Next month's bill was incorrect. 
14. Following month's bill - Told again monthly bill was incorrect, applied a $25 credit, and told it would be fixed going forward. False. Next month's bill was incorrect.
15. Xfinity reached out to me regarding my complaints to the FCC. Told billing was correct because they removed Netflix after getting my approval. False. I was never told they were removing Netflix, which costs around $25, as part of the special promotion to save $25. I was told repeatedly there was no change in my existing services and removing Netflix was never mentioned. When I asked them to share the pre-approval documents that were presented to me during my initial call and the transcripts of my calls, I'm told they do not share that information because it's proprietary. 

I strongly believe Xfinity has been dishonest with me and their unwillingness to share the pre-approval documents authorizing the removing of Netflix as well as their unwillingness to share the transcripts of my calls raises serious questions of regarding their honesty with their customers.
