FNB quick sell - ombudsman, or banking tribunal, anything to report this horrible service

I have had the worst time with FNB quick sell, the consultants as well as the various attorneys selected I would like to make a formal complaint at Ombudsman and would please like some guidance of how to do this the transfer / registration of this property from the time I was advised was sold took 7 months as a result, I could not place a tenant during this time, I had attorneys be extremely rude and could not get hold of them I was held liable for lapse in costs for clearance figures etc I was waiting on the transfer to go through before making complaints as I was very well aware that they could delay this even further this has had a terrible financial effect and strain on me due to the really terrible service received and I would never want anyone else to go through this ever again FNB needs to jack up from start to finish this has been traumatic I would like it to be noted that the attorneys selected should never be used again clearly they do not have capacity and its unfair Ono the client to deal with this alone
