Free Peacock subscription reward error

After almost an hour on the phone my issue was not resolved. A ticket was opened which I do not suspect will be fixed. The representative gave me wrong info. Then offered me a $14 credit on my bill, but said my next month's bill would increase by $7 from being "prorated". HORRIBLE experience. I told him I do NOT agree to my bill changing. [Edited: "Inflammatory"] the $14 credit on this months bill if it means my future bill will increase. Xfinity is a greedy corporation who only cares about nickel and diming their customers instead of treating them correctly. Rohit was the employee who gave me horrible service, didn't sound like he knew anything and then tried to charge me more. I got an email 2 days ago about "claim your peacock subscription at NO EXTRA COST" for being a platinum customer. First Rohit told me I am not a Platinum customer and that offer was for a different plan, I signed into my app and reviewed my account confirming that I am a platinum. Then he tried having me sign up for the reward through the full website which also did not work since the app kept telling me "looks like you're not a member of the program yet" and the link to Join Now has not been working for 2 days. Then after another hold he came back and told me I am eligible for the free peacock subscription but it was not working because of a technical issue on Xfinitys end. Which I tried telling him from the beginning. If this cannot be resolved I am changing my internet provider and cell phone carrier.  Horrible horrible service.
