Billing Dispute: Extremely Frustrated

Seems like there is no way to send an email, thus I am posting here. I am extremely frustrated with how my billing dispute has been handled. I previously had a $40 promotional rate, and when that promotion expired, I contacted Xfinity specifically to find out what options were available.

Your representative told me that if I signed up for the new deal, I would temporarily pay $55, and that after 10–12 days I could switch to a new promotion that would bring my bill back to $40. I was also clearly told that any extra amount charged would be credited back to me. I proceeded with the change based on those specific promises. I was also told that the $80 monthly amount shown on my account was temporary and only for reference and that I should not worry about it.

I want Xfinity to go back and check the chat history and see what was promised. I expect Xfinity to correct my billing and apply the appropriate credit. If this cannot be resolved immediately, please escalate this complaint to a supervisor or the appropriate billing/customer-retention team. I will be canceling my line if this is not resolved.
