Have to wait 15days for Capitec to fix their mistake

I bought airtime and data through Capitec on 16/4/2020. I did receive a sms for the airtime and it was received but the data I did not receive a sms for nor was it received but the data and airtime went of my Capitec account ad paid. I phoned Capitec ref no ***6 and was told to wait 24 hours. 17/4/2020 (24hours later) I phoned Capitec again ref no ***9. This time I was told to wait 14 working days and then phone back. I paid the data, the elderly lady I bought it for is without data, alone in lockdown. I asked if the person could assist me it purchasing data through Capitec so that it will be available bit she said that she could not and I could try the app again but there is no guarantee it will not happen again. I really think its unfare to wait half a month for there mistake with my money.
