DISGUSTING SERVICE

I have been an MTN customer for 17 years. When my MTN contract was handled by Autopage, service was an absolute pleasure. Over the past 4 years since MTN have taken back managing their own services, it has been nothing but a nightmare. I have had ***** on my account, logged a call, still not resolved as they do not get back to the customer. MTN made an error with my billing and 3 years later then told me I needed to pay for their mistakes, after much frustration they agreed to write off 50% of the "debt". Now they have changed their billing system and the account is in a state of disarray yet again. MTN billed me incorrectly, they failed to send me invoices for 2 months and now once again I am held liable for their incompetency. Once again my services have been disconnected and payment has been made! I have tried to call the call centre and have been holding for almost 2 hours, and the call does not get answered! But should you pay your account R0.05c short and they disconnect, then again when you pay R2,200.00 they also disconnect, MTN have absolutely no sense of customer service.
