MTN bad network!!!

I have 4 contracts and every month one of them have a problem. This month my voice mailbox stop working suddenly and if I want to send a sms it tells me no airtime, but I have airtime and 579 sms in my sms bundle. I phoned the customer service 3 times and the first time I was gut of after almost an hour on the phone. Then they tell me I don't have the service on the line ( but I had it for the past 18) and it need to be added again and I have to wait 24 Hours. 24 Hours later and the voice mailbox still doesn't work. Call again and now there are 2 mail boxes and a call for this fault is logged again. Again I have to wait 24 Hours. And every time when n Usd is logged no feedback from anyone. I have to phone again to follow up the problem and spent another hour or two on the phone with yet another consultant who has no idea where the problem start.<br> <br> I just had enough of MTN between data disappearing and when you phone they just tell you, you used it but the phone was off, faults on the accounts, voicemail problems, sms that can be send, I wonder what do they rate their services. Perhaps I must migrate to another network!!!
