No response - No assistance

I have been a MTN customer for years. This is the first time.as a contract holder that I have constant problems. I can either not access internet and now cant make calls because my air time is finished. Have been into Sandton and Gateway for assistance. Both branches tell me they cant help I must call 808 for help. This is day 3 and either the calls never get answered or the call cuts off when selecting 0 to speak to a operator. I cannot make a single call and noone willing to help. SHOCKING!!!
