VERY POOR SERVICE RECEIVED

I have numerous calls with regards to problems that I am experiencing with 2 of my MTN contracts:<br> <br> 1) Contract 1:<br> *** (12/7) & ***9 (13/7). I upgraded my phone to a contract of R229. My new bill is R440, without me going out of my limits, this is the normal rates and they are incorrect. Also I have not received my 200SMS bundle and my 300MB data bundle, and I am billed for them? I have logged the issue on e-mail, MTN active, and I have tried to phone the call centre several times, but I hold on for hours without any response. This is truly dismal service that MTN is providing.<br> <br> 2) Contract 2:<br> <br> Ref: *** (12/7) & ***4 (13/7). There is a problem with this contract, every second call is diverted to a distorted voicemail without ringing even once. We have tried numerous things but the problem persists. and MTN is sending me from post to pilar
