Product: Debt collection

On XXXX, I called XXXX to see what upgrade promotions my account was eligible for since I had been with them for 5 years and new I should be eligible for a new phone. I had both cellular service and home internet with XXXX and up until XXXX, I had been happy with their high level of customer service and ability to handle any issues. However on XXXX, I spoke to a number of ill-advised individuals that told me my account was eligible for nothing. I spoke with a representative named XXXX in XXXX, that was very rude and unknowledgeable, he did not seem to know what the Retention department was or that it even existed so I removed my account from Auto-pay and advised I would be switching carriers. In the 5 years, I had never been late on a bill and due to the XXXX billing system, services were paid for a month in advance. On XXXX, XXXX ported my number out from XXXX and switched to another XXXX. Since I cancelled prior to the next bill date, it should have resulted in a prorated amount at least for the cell phone line. On XXXX, I called XXXX XXXX XXXX to inquire what would happen to the Internet line since I had ported my number out. I spoke to several individuals on that day : XXXX and XXXX, who demanded I pay XXXX or they would cancel my XXXX XXXX line. Although he did admit the billing needed to catch up and that a prorated amount should apply. I was not able to see the billing at this time and the only information I received from XXXX XXXX were threats. Then I spoke to a supposed XXXX named XXXX in XXXX. XXXX would not provide any credit on my account but stated the bill would get updated on XXXX. Since they were so rude and unprofessional, I told them to cancel the XXXX XXXX at the end of the billing cycle on XXXX. I had XXXX in XXXX XXXX send me a return label for the internet equipment via email. I did return the equipment and did receive a confirmation email from XXXX they received it. I was expect the prorated amount refunded back to me in the form of a check however instead I received a debt collection letter from some company in California demanding {$160.00}. This was even before XXXX sent me a final statement. Since then XXXX has XXXX sent me invoices demanding {$130.00}. For what, I do not know. I also started receiving collection calls from a AmSher Collection Services in Alabama, demanding {$160.00}. This happened around the same time I received another statement from XXXX asking for XXXX. So on XX/XX/XXXX, I called XXXX and spoke to XXXX, who acknowledged XXXX owed me money but would not say how much and then a supervisor named XXXX, who stated XXXX was showing {$160.00} due, that my account was locked and they could not assist me. So then the called AmSher Collections and first spoke to a XXXX, who refused to identify the name of the company and disconnected the call. I then called back and spoke with a female who at least provided the name of the company. I advised her to remove my number from their list and not to contact me again. I do not know why XXXX XXXX ended up in the toilet however I will not put up with being treated like garbage from an organization that I pay. I thin XXXX is also responsible for a security breach of my personal information in XX/XX/XXXX that has cause me additional issues. My information was leaked on the dark web, XX/XX/XXXX, XX/XX/XXXX and XX/XX/XXXX. The XX/XX/XXXX leak was not reported to me by XXXX however I know a large breach happened on their end that affected a lot of customers. I will not be paying this " debt '' as the only debt is what they owe me. Now my personal information was given to other entities and I do not appreciate it. It should be noted that since XXXX sent my account to a debt collection agency then they should not be sending me any invoices or any additional attempts to pay them directly. Either way, they are not getting paid and I would like to be refunded as I am due.
