Billing

MTN, as a loyal customer for past 4 years I am disgusted at my current billing process. My current bill is close to R5000 for October, where as previously my bill has been R769, this is unacceptable. You have failed as a service provider to communicate to me that my account has now been switched over to a new system, and that my usage limit has increased. I refuse to pay my account until this matter has been sorted. Failing to do the above, I will then have to take the matter further. Either to Ombudsman or Hello Peter. No communication has been sent to me stating new system changes. Kindly rectify my billing account urgently. A call back from your accounts department will be appreciated
