WORST BANK EVER

I have never experienced such service from a financial institution. Yesterday, I transacted on my app and purchased 2 R30 ott vouchers. Money was deducted; however, I did not get the PINs. I called FNB and was told to resend it from the app. The more I explained in that there was no voucher pin given How do I resend something I did not get? I was told the matter would be escalated, and still, nothing. I called again and spoke to 5 different consultants. I was given a ref numbers and told to call OTT myself which i did and was told that FNB GAVE ME THE WRONG FREAKING REFERENCE NUMBER. I am being so inconvenienced for a mere R60. I am fearly new and this bank service sucks. really for a flipping R60.CAN I JUST GET MY DAMN R60 BACK
