All airtime already paid for ****** when migrated

Hi Cell C,<br> <br> Another complaint about you, that's 4 already in my 22 months with you.<br> <br> I requested to be migrated over to prepaid but all my airtime and data which was already paid for was removed off my account.<br> <br> IS this a case for the Consumer Council or will you be refunding me these amounts in my next bill?<br>
