No response to my credit enquiry after it was ok by vodacom

It is now almost a month after I was phoned and told that they listened to the recording and I was right they will pass a credit up to today it is like nobody knows what is going on no credit just death still there is no way you can phone the people that promised the credit cause vodacom only deal with emails in this dept you can't phone them I wrote a email everyday just a waste of time no I will not recommend anyone to vodacom just want to cancell every contract that comes to an end starting with the 2 in June I am tired of vodacome and their empty promises.
