Slow service

Early this year I was given a call by Eugene from GI Inc sent by FNB regarding an amount I was paid the owing FNB for Temp loan. I made arrangements to pay R350 over three months which was March, April and May. On my last payment OI found out that I over paid the lawyers. I asked for the money I overpaid not to be deposited to my FNB account as it was in errors and rather they deposit it in my Capitec account. Eugene said they could only do that if contacted by FNB as they were their client. Lucky from FNB phoned Eugene to make arrangements for payment. Eugene phoned someone who is in FNB head office and gave me feedback that it was in process. I phoned again early this week to find out when I'm getting my money and Eugene said they were working on it. All I want it my money as I have to use it Monday for transport. I took out my own cash from my pocket to close the FNB account of which I had to use that money I paid over with. These lawyers were quick in telling me to make payment but now their delaying to refund me my money. It is my money I want it back. Eugene ***
