Mega u account

I opened a Mega u account for my daughter, so they don't earn interest on their account but they get rewarded with vouchers... Or apparently so. I have had issues with downloading the data more times than I wish to remember and when I get frustrated enough I send a complaint and we then receive our data. It is R12 worth of data but takes me an hour of my time to get organized. I have tried food vouchers with Debonairs now, but when u put it in on their website it does not work. I have tried the app, phoning the *# number nothing works. If your system doesn't work fix it or don't have it, but right now all u doing is lying to my child. I'm seriously considering moving her money as this frustration is just not worth it. It's not teaching them to save or enjoy their rewards!
