Retention Pricing request

I called earlier because I cancelled my cable subscription and was prepared to cancel my internet service and switch to T-Mobile. I was told there were no options to lower my $80 monthly internet-only bill, which is disappointing because I would prefer to stay with Xfinity. T-Mobile is offerering 500 GBPS for $35. I am asking for a retention specialist to review my account and see what loyalty promotions or lower-cost internet-only plans are available. I am looking to get my bill closer to $35-40 per month, and I don't need cable TV. If Xfinity can offer a competitive rate, I would much rather keep my existing service than switch providers. Can you please review all available options before I make my final decision tomorrow? We are only in the town for the morning tomorrow and need to make this switch before we leave at noon. Thank you!
