I received a telephone call from PMAB , LLC of XXXX NC on XXXX/XXXX/15 notifying me of alleged medical debt. After verifying my address and phone number, I informed the representative that I would like proof of the debt and that I had no intention of paying the alleged debt until I was shown proof. He told me he would send proof. I subsequently received a " XXXX % Offer Letter '' dated XXXX/XXXX/15 ( which is not proof ), and missed phone calls from PMAB 's number XXXX on XXXX/XXXX/15 ( XXXX ), XXXX/XXXX/15 ( XXXX ), and XXXX/XXXX/15 ( XXXX ). At no time did the company leave a message or identify themselves via voicemail. On XXXX/XXXX/15 after receiving the final missed call from PMAB, I contacted PMAB to obtain their fax number for correspondence. I was given XXXX which I confirmed with the XXXX. I drafted a cease and desist letter and faxed it to PMAB on XXXX/XXXX/15 XXXX. Fax confirmed the transmission was successful. Subsequent to the faxing of my cease and desist letter, I received yet another phone call from PMAB XXXX days later on XXXX/XXXX/15 ( XXXX ). This time, a message was left. I promptly returned the call and spoke with a female representative who informed me she was calling regarding " medical debt. '' I informed her that PMAB was in violation of the Debt Collection Practices Act because I had previously faxed a cease and desist letter and yet received another call. She stuttered for a moment and stated " well that letter is n't in your file ... it must have gotten lost on the fax. '' I told her that I would be filing a compliant with the FTC to which she responded with " yeah, well, that 's fine ... whatever '' and then promptly disconnected the call.
