benefits given yet taken away.

Yet again another report about mtn. So on the 21st of each month i get my airtime and my sms' . however this month MTN gave me these benefits but 2 days later took it away. I tried calling the Call Centre to get an explaination as to why this has happend but unfortunately there was no answer from them. <br> <br> I am fed up of this and i will like a senior representative from MTN to give me a call on *** alternatively email me at [Email Removed]
