Standard Bank airtime purchase app design flaw

On the 11th Dec I made two R500 Airtime purchases - The first one I correctly selected MTN. On the second purchase of R500 I forgot to select MTN and as such my account was debited to CellC which is the default service provider on the app if you do not change this. (I have always entered my correct cell number)<br> <br> I logged this issue with Std Bank on Sat 12th Dec.<br> I have since called the bank 3 (THREE) times for a resolution and keep getting told that it is my mistake and I lost my money. So basically from this deal I have sponsored Std Bank and CellC? I don't think so !<br> <br> Seeing that fellow customers have had positive feedback unfortunately AFTER posting on our beloved Hello Peter website (The only true service provider that stands up for us in times when dealing with difficult service providers) I have decided to use this medium to get results as 4 weeks to resolve my issue is just too much. (I am a patient guy what can I say)<br> <br> Thank you<br> Looking forward to getting my money back.<br> Kind regards<br>
