Escalation - Unresolved Disputes

I have logged a dispute for two transactions since the 25th May. I am yet to receive proper feedback or a chargeback. I've been sending the same documentation more 5 times, only to be requested again and again. There is no resolution to my submissions. We are headed for month 2 of my submissions. How does FNB allow this to happen to loyal customers? I have had it, and I am being forced to carry this through to Ombudsman for Banking Service South Africa; as result of the non adherence to the TFC policy. I have been patient for a long time.
