bad service

I have been unable to get hold of the MTN SP Insurance department since last week. After phoning and supplying your cell number they simply cut-off your call saying \they have temporary network difficulties". <br> How is it possible for a cellphone company to be having the same problem since last week.<br> I was however warned by the MTN Service repair centre that I should rather email the insurance department as they never answer their calls. <br> This is totally unacceptable - the exact reason why I hate phoning a call centre !!!!"""
