Bus booking issue not resolved

Good day

I have been sending numerous emails following up on this with FNB. Unfortunately, last week Friday 04th of April, I was told that my emails were not received, and this case will be closed. I then called immediately and was told that Phindile will call me back, again Saturday 05th I was told the something. Today after calling FNB and was given a number to call eBucks of which I was not helped as the payment was made through FNB App and not ebuck account.

FNB told me that they can't assist with EBucks queries and eBucks said they are not affiliated with FNB and therefore they can't assist. Where am I supposed to request my money from?
