MTN NEVER WILLING TO ASSIST!

MTN NEVER WILLING TO ASSIST.

Upgraded 2 contracts that I have with MTN and while in store needed to change the account holder from myself to my mother who is taking over the account. MTN has failed to do so and the account is still on my name whilst the Debit also goes off on my account. They gave an excuse of my mothers ****en surname not matching on their side however she has AN EXISTING ACCOUNT WITH MTN!!!! I tried calling in and they advise we should go in store. When we go in store they advise to call for help. This is not the first time I'm having to come on this site seeking help regarding MTN and their account issues.

I simply need the 2 contracts to be moved over to my mothers EXISTING account. Why does such a simple process need to be this complicated ?
