Does the Legal Department exist

I have tried on numerous occasions to get in contact with Mtn’s Legal Department to get my account closed and a settlement letter. My account has fallen under Section 14(1) of the Prescription Act 68 of 1969: but nobody seems to be able to assist. I have sent numerous emails to their Legal Department only for them to tell me they can’t pick up my account no but I am being harassed by their Debt Collecting company.” Many consumers don’t know by law they are not obligated to pay an account if three years have passed even though Debt Collectors tell you otherwise. Is Mtn becoming ************ like their Debt Collectors they employ.
