Xfinity Employee [Edited]

I called Xfinity on 5/31/24 to cancel my tv service but keep my internet. Without telling me, the employee upped my internet service and put me into a new contract. Once I realized what happened, I immediately called back and demanded that the contract provision be removed which I was assured it was. I called on 6/11/24 to cancel internet and was told by a manager that in order to cancel my service without incurring a cancellation fee, I had to pay my balance owed immediately. He also said that it had to be done with a credit or debit card and couldn't be charged to my bank account on file with Xfinity. That should have been the red flag but hindsight is 20/20. I gave him my credit card info and he sent me a text asking me to confirm the authorization for the charge. I then received a text confirming that my payment had been made. Fast forward to 6/19/24--I get an email from Xfinity stating that my payment was returned by my bank account ending in a number that doesn't match any of my bank accounts--and I didn't make my payment using a bank account--I used a credit card. So I hop on my credit card account and see that a charge to "Utility Savings Hub" was made on my account in the amount of the supposed Xfinity payment. I disputed the charge with my credit card company and am now in a battle with Xfinity. I don't know if they simply don't care that they have an employee who is fraudulently getting customer credit info or if the language barrier WITH EVERY PERSON THAT I'VE TALKED WITH is the issue.  There is no company that I despise more than Xfinity and while I'm thrilled to not have to deal with them any further for tv or internet, thanks to their outsourcing customer service to the middle of nowhere for pennies on the dollar, I can't be fully done with them until this fraud issue is resolved. I will never use Xfinity again and I will tell every person I know not to use them and why.
