MTN has the Worst Customer Care Service in SA

Two years back, I accidentally locked my voicemail and had to give a pin to login. I called customer care and I don't know what the lady did, but I can't access my voicemail at all.<br> <br> Everytime I call 100 or 120. I get the following message \Your voicemail is not available right now, please try again later.\"<br> <br> So I called MTN four times with no feedback or help. The last time I called their system was down, I asked the man to please call me when the system is online - he gave me some kind of lame excuse.<br> I emailed MTN four times, no help - indeed most of the time I have to give them specific instruction of what I want them to do. All I want is them to deactivate my voicemail and reactivate it again and if that doesn't help to deactivate it totally, so that nobody can leave me message that I can't get back to.<br> <br> I even complained on Facebook, twice! I am so completely fed up, that I have already decided to move over to another service provider the moment my contract has expired. I've been a customer since 2001 and even Telkom at least comes back to me after two month."
