MTN disgusting service

My husband signed new upgrade contracts with MTN for both my son and myself on the 5th of September. the contract was for 100 minutes airtime, 200 sms's and 300mg data per month, and as a special promotion 1GB per month for the first three months (valid for 30 days). Both contracts received only the pro-rata airtime for September, and after enqiring at the Durbanville MTN branch, I was told that the extra's would only begin at the beginning of the new month i.e. 1 Oct. <br> By the 2nd of October again only the airtime had been received and after numerous phone calls, the sms's and 300mg data was received. No 1GB as per the promotion. After more phone calls the promotional data was loaded on the 15th - valid for 7 days and promptly disappeared on the 23rd. The very same thing happened in November. In the meantime there have been hour long phone calls where MTN consultants blatantly call their clients *****. Not only have we not received the data, but the cost on our airtime is exhorbitant and is MTN going to re-imburse me for this. Never, they just ***** more and more from their customers.
