No airtime

I tried to buy R30 airtime on the 29th of October, the app kept on rejecting my request, when I checked my statement 3 R30 airtime transactions were charged but I never got the airtime to this day. When I checked Facebook I realized I'm not the only person with this challenge, we complained but Capitec is not responsive. I am done with this bank, first thing tomorrow morning I'm going to accept Discovery Banks offer for a bank account and that's where I'll receive my salary from. I want my money credited back into my account, I will then withdraw it and close the account.
