First National Bank

I have been trying to query a payment I made to a relative at another bank. Since the 26th August they still have not received it. One FNB tells me it is the other bank suspense account, another tells me I must phone RCS Credit cards, another tells me to phone Standard Bank, another tells me about a completely different transaction. Nobody seems to look into it properly. I have already given notice on my Investment account and will be closing the rest of them if no satisfaction received.
