Shaipro Shaik shaking down consumers

I migrated from MTN to Telkom when Auto Page sold thier book to them. I was not allowed to migrate until I settled my outsyanding balance with them. I had not had communication from MTN for more than six when suddenly since last year I have had a barrage of call from Shapio Shaik demanding that I settle an outstanding account or I will be handed over. I have requested the so called account to be sent to me, but this has not happened. Shapiro Shaik harrass consumers who otherwise do not know their rights and force them to pay debts which are inot legitimate. Shapiro Shaik are ********* and so is MTN, MTN have obviously sold a Debt book that has paid up accounts on it, and Shapiro Shaik use Mafia type tactics to harrass unsuspecting consumers.
