XXXX XXXX XXXX has been my Cellular Carrier for about 20 years. I 've always made every payment on time. I had their sister Company, XXXX XXXX, for awhile and due to problems, had to have it disconnected. During the time I had XXXX, it was combined-billing with my XXXX XXXX XXXX Cellphone Service. Sometime after cancelling XXXX, I began receiving notices from various Collection Agencies that I still owed XXXX XXXX XXXX for their Services. I contacted both XXXX XXXX XXXX and XXXX XXXX Customer Service, and they XXXX told me they showed no outstanding Debt on my Accounts. XXXX XXXX XXXX continues to harass me via XXXX Collection Agency after another, yet can not provide any proof of exactly when, where, and what the outstanding debt they claim I owe is for. The latest harassment is from a company called ERC, address is a XXXX XXXX XXXX XXXX, XXXX, FL XXXX. I believe it is illegal to operate a XXXX XXXX XXXX out of a XXXX XXXX XXXX, a violation of Federal Law. XXXX claims that my debt owed is {$84.00}, for XXXX XXXX XXXX Account XXXX XXXX, which is not my current account number, although I have had uninturrupted Cellphone service from XXXX XXXX XXXX for approximately 20 years now. ERC Collections Reference Number being XXXX on their latest letter to me.. I have had about XXXX Collection Agencies over the years, hounding me for this money, and every time I contact them and explain that XXXX XXXX XXXX has verified with me by phone calls to their Collections that I owe no money, the Collection just gets sent to another different Collection Agency who begins the harrassing letter process over again. I have responded to these Agencies in writing several times, refusing to pay anything, based upon my conversations with XXXX XXXX XXXX and XXXX XXXX both stating that I owe nothing. This continuing harassment for no proven valid reason has damaged my Credit Rating, and at this time I request followup investigation, and notification to XXXX XXXX XXXX and all Collection Agencies past, present and future involved, that this is a Complaint for unjust harassment without substantive proof, and that they are to immediately sease and decist, and that I am entitled to any and all reparations under the Law for their conduct towards me, and for the continued non-stop harassment that I have encountered over the years, due to these Companies falsely accusing me of oweing money without any substantive proof of such, and despite my repeated phone calls and letters to these Companies, who have XXXX agreed verbally that I owe them no debt, but have failed to remove me from Collection Agencies rolls,, promptly and properly, per all Laws XXXX State and Federal. Further, I request that all resulting correspondence of any nature be addressed to me in writing and sent to me, and that it contain a name, department, and phone number of any employee seeking any information relative to, and or pertaining to, any aspect of this entire matter. I also request a receipt of confirmation in writing, for this complaint I am hereby filing.
