******** CREDIT LIMIT

I did an upgrade on my one cell number this morning, dealing with Leeann, who was very friendly and helpful. So, lo and behold, not even a few minutes later I receive an SMS from MTN stating that I have exceeded my credit limit of R764.00. ***??!!! I do an upgrade and the next moment I have a credit limit on my account? On whose authority? Sure as hell not mine - I've never set a credit limit on my MTN in the 12 years+ that I've been with them, so who the hell gives them the right to do it?????!!! I WANT THAT CREDIT LIMIT REMOVED IMMEDIATELY, AND THE IDIOT CALL CENTRE AGENT THAT I SPOKE TO AT 09:30 FIRED BECAUSE SHE'S A BRAINLESS DIMWIT WHO RECITES WHAT SHE HAS LEARNT IN TRAINING AND IS UNABLE TO THINK FOR HERSELF. Telling me that I have to change the limits on my phone dialing the *141* ... number. EXCUSE ME??? MTN stuffs up my account and then I have to change things. ***** that and ***** MTN. I have two cell phone contracts due for upgrade and then expiry shortly thereafter - either MTN sorts out their stuff up and apologise for their incompetence and sheer stupidity, or I cancel those contracts. Many other service providers out there ....
