How long to wait for airtime to be recharged?

On Friday morning 30 January 2015, at 10:45am and 11:07am I made 2 payments of R100 each on MTN Active to top up my airtime. Reference numbers *** and ***. Up to date (101 hours later), after the website says 15 mins, my airtime still hasn't been topped up? I made a phone call on Friday afternoon at 14:30 to report it to number *** which is given on the confirmation email, and I was informed someone will call me as to settle the problem or refund me. I haven't received an email or phone call since then. Then I phoned customer service 808 on Monday as *** didn't work. I was informed that they will log a query and that it will be dealt with urgently. Ref no *** and that it will be resolved before end of the day. Nothing was resolved. I phoned 808 customer service numerous times today (Tuesday) They couldn't help and kept putting me through to 1761, MTN Active that was never picked up or were just cut off. I've sent emails to mtn's customer service and MTN Active. Still nothing. Since Friday I was unable to use my phone as the airtime still hasn't been topped up. I've paid, and yet still nothing and no service. How will this be resolved?
