Incompetence

As a loyal customer of MTN SA and an account holder with two devises, I renewed my cell phone contract early Feb 2015 as I comfortable and never experienced any problems with this service provider. I did the renewal through the Brooklyn branch, because this was the only branch around Pretoria which had the mobile phone I preferred. I completed the necessary documents, signed and initialled were applicable. I then requested the consultant that was helping me to ensure I remain on Prepaid option as I always have been since the start of my contract existence with MTN. The total amount due to MTN for both devises was R650 which I NEVER EVER failed to pay!<br> <br> I then discovered 2 months later that this was not the case when I realised a sudden increase in the monthly debit order fee. It first started with an increase of R800, then R1400, now I am expected to pay R5000 end of June. The debit for R1400 went off on the 25th of May and the next day my outgoing facilities were suspended, without any prior notification nor explanation. I then went to the nearest branch (Mall @ Reds) to get answers, frustrated as I was no one had any. I demand an immediate termination of this USELESS contract!
