\Call unstable\" messages"

Well I find it absolute surprising to see that no one has complaint about this yet today!!! I have had for three days now been unable to make any calls with my MTN contract phone and keep getting the message \call unstalbe\" and it just cuts the dialling off or else, when someone phones me, it drops the call half way!!!!! This has been very frustrating and I have been to an MTN shop in the Shopping Mall here in Port Alfred, where I am visiting to be told that they have had \"hundreds of clients in over the weekend with the same complaint but they cannot help as MTN has not told them what the problem is, only that there is a NETWORK PROBLEM\"!!!!! So, all is kept in the dark and I find this totally unacceptable to be treated with such contempt by MTN!!!! How do one do one's business if you cannot make any calls because the \"call is unstable\"?????<br> I am totally fedup and yes, no other cellular company is much better from what I hear as Vodacom has also had problems last week. So, phone calls are being dropped/disallowed in favour of selling internet data packages to all and sundry without extending their network services and South African consumers have no recourse!!!"
