Unable to receive calls from MTN network phones

For the past two weeks I have been unable to receive phone calls and sms from a person using MTN. <br> <br> When a person calls me it just says: \The subscriber you have dialed is unavailable...". As far as I could figure calls from other networks are fine. <br> <br> I have logged a call with the call center and have now been told that everything looks fine and to log a call with MTN myself. <br> <br> This is unacceptable as I now have to attempt to log a call with a company that I have no contract with and still having to 'pay' Vodacom for the phone calls to MTN as well."""
