ABSA MegaU - WHERE'S THE BENEFITS?

My two children have had Absa MegaU accounts for more than 18 months and every month since the opening of the accounts they have qualified to receive 'benefits'. To date we have not managed to claim a single time! Every time we have tried to contact the call centre the phone just rang indefinitely. Once when on holiday in Durban we tried claiming movie tickets - it was impossible. Then some while back I received an sms informing of the new way to redeem via the online megaubenefit page.... guess what -after about literally 20 tries punching in both the kids id numbers etc. - each time the response was 'no vouchers available'. My son waited till the 10th of the month and we tried the online site again. We opted for the McDonald voucher. We received a response saying that an sms will be sent to us. Three or so days later (yesterday) I finally received the smses with the voucher pins - finally they could use their reward for saving with ABSA... or not! Today we decided to for an end of exam treat and use the voucher only to find after several tries by a 'bothered' cashier that neither of the vouchers were working and after much embarrasment I paid cash for the order. I researched all the major banks before deciding to open accounts for my children at ABSA and these 'rewards' to encourage them were one of the deciding factors. How will ABSA compensate my children for all the months that we have tried to claim this non existent 'benefit' or will they even care? Please stop with your false offerings and ABSA PLEASE STOP CHEATING OUR CHILDREN!!!
