Taking Chances on Prescribed Debt

I got a call from a rude consultant about NSFAS, never acknowledged nor received a call from any credit provider in 15yrs ,i dont know about this account and its prescribed according to NCR act.

Please remove me from your contact list

Amendments to the National Credit Act specify certain requirements when potentially prescribed debt is being collected on. This in practice requires a debt collector to ensure that a debtor is aware of the defence of prescription when attempting to collect on a potentially prescribed debt. This is prescribed - stop doing ******* things

Also send a electronic file to the relevant credit bureaus, for my profile to be amended.
