MTN doing nothing to stop *****sters

Received another call today from MTN ***** telling me an attempted SIM swap had taken place, an attempted ***** of course, told the guy to F#@& off, the problem is that this happens regularly just after my account is credited with data and minutes. This means MTN's customer data is not been protected by MTN, time for a smart lawyer to take them to the cleaners for virtually assisting *****sters.
