Appalling Service by XFINITY

I called Xfinity end of May'26 that I want to disconnect my Broadband from 6th June'26 as I was Moving to South California and Xfinity didnt had their service available. Request was take and infact I got a call to confirm and go through the same Question Answer again, I got email saying the request is taken. 6th June'26 I returned my Router to nearest Store and I was given a Receipt, 10th June'26 When I was trying to check I suspected that my Internet is still active. I initiated a chat this  time and found a [Edited: "Inflammatory"] Agent - [Edited: Personal Information] He wasted almost 40+ mins and did disconnected the Service however didn't responded anything so I wasnt even aware he has done something. When I called this time call landed in Manila and the lady was Rude she wasn't even trying to understand the issue.
