I had cancelled XXXX phone line XXXX years ago, but kept the line for my daughter to use XXXX. We cancelled this line after paying in full at the beginning of this year. I 've endured numerous phone calls from XXXX XXXX since. I 've been told the XXXX number was on hold due to my being XXXX but had recently been re-activated ( I never have been in the military and never told them this ), and I 've been told I owe everything from {$100.00} to {$16.00} to {$47.00} ; sometimes their reps were rude and aggressive. Every time I called them, I had to wait on hold, sometimes for over an hour, to speak to a service rep. and each time I called I got a different story and a different payment amount. Each time I called, I requested and was promised documentation of the call. Sometimes I requested and was promised an email which of course never arrived despite repeated follow-up calls on my part. XXXX XXXX just kept sending me bills in different amounts as if I 'd never called. Now it appears that XXXX XXXX has engaged the services of Chase Receivables, a XXXX XXXX XXXX in XXXX, CA who have written with a demand for payment. I sent them a request for documentation and received no response. I then sent them a formal dispute of this charge and wish to ensure that my credit rating is not affected negatively. I cancelled my accounts and paid in full, only to have XXXX XXXX continue to attempt collection in various amounts over the course of over 4 months. I simply do not owe them this money and they 're just hounding me until I give up and send them a payment to make them go away. Disgusting way to treat a customer.
