DMC harasment!

DMC- ********** 57. Stop harassing me for prescribed debt. This is now my 3rd request: Refer to ND ********** 7 June 2018. You are in contravention of the NCA Sec 126b. It states that no person may continue collection or re-activation of such prescribed debt as a prescription Act 68 of 1969 (Prescription Act). I request this matter be closed. Any negative information will be removed from my credit record. Should I receive any calls I will lay a complaint with the relative authorities. Please attend to this matter at the soonest and send a Prescribed letter that this account is closed to me. DMC responded on HelloPeter that they send me an email re my previous complaint - but used incorrect email address. I will get legal advice as to stop this harassment.
