Airtime beeing forfeited

I realized that my airtime doesn't carry over to the following month anymore (it always did in the past)<br> I logged a complaint and I was told that it carries over for 6 months, which it didn't. When I upgraded my contract on Sunday the 25th of October I asked the lady to check for me and she was the second person that confirmed that more than R400's airtime was forfeited that was supposed to be carried over. She logged another complaint for me, I was told I would be contacted within 2 working days which didn't happen. its 5 working days already. Ref no 53-9J52K-K4UBZ<br> I want that money to be paid back to me.<br>
