R200 AIRTIME NOT LOADED

I purchased prepaid landline airtime for R200,00 which after a while I realised was not loaded. For two weeks now my wife and I have been sitting on the phone being thrown from pillar to post re who can assist us trace the voucher number and credit us with the same. We call the main customer service line and transferred to sections which in turn transfer us to different section and especially the prepaid section is so clumsy that they either send one back to main line which throws you back to them and quite often then they place one on hold and eventually they hang up and/or one hung up because one has other things to do rather than be on hold for ever. Please help us.<br> <br> The voucher number is ***<br> Tel: Landline ***<br> Cell: ***<br> Cell: ***
