Simple & Easy isn't Simple and easy as one would expect

I am seeking clarification regarding my services, which were previously priced at $88.62 for Peacock Premium and the Ultimate TV package. I attempted to add Cinemax, but my initial bill indicated that this would not be feasible. I assumed that canceling Cinemax would allow me to revert to the original price of $88.62. Unfortunately, this has proven to be more complicated than anticipated. I have engaged with Xfinity chat representatives on multiple occasions, including last night, in an effort to resolve this issue. Ideally, I would like to maintain all Xfinity cable and internet services within the vicinity of $88.62, inclusive of Peacock Premium and the Ultimate TV package. I understand that pricing deals and discounts can fluctuate; however, I am perplexed as to why the original offer is no longer available, given that the Cinemax addition was made around the 3rd of July. Could you please advise if it is possible to reinstate the original pricing and package? If not, I will need to accept this outcome, albeit with some frustration.
