MTN also committing ***** in RSA

I am in disbelief over how bad the customer service at MTN has become. I requested a number change a month ago - the sim card was not changed - just the number. I had 2500 minutes, 1.2GB's data and 300 SMS's on my old number which were supposed to have been carried over to my new number. A month later this has still not been done. After numerous calls to 808 and numerous visits to Forest Hill Direct MTN store this issue has still not been resolved. It just keeps getting worse. MTN have also failed to give me my contract allocation for the month. Every time I call in the issue gets escalated and I get given another reference number but no resolution in sight. This is ***** - MTN have ****** my carry over minutes, data and SMS's and have failed to abide by the contract by not supplying me with my contract allocation. It seems to be common practice with them if you read what is happening in Nigeria. The final straw is they have now decided to simply change my debit order date - without any consultation!!! This is *********. I have been a loyal customer for more than 15 years - never missed a payment - and this is how they say thank you!!! Utterly disgusting!!!
