FNB service unacceptable

I am extremely disappointed in the service of FNB. I settled two of my personal loans on the 1st August directly into the accounts via EFT. I went online into my banking two weeks later and the amounts were still reflecting as outstanding balances. I then phoned them and spoke to a call Centre agent who then asked me for proof of payments to be emailed to her and said she would send it to the allocations department. At the end of August I was still debited for these loans which is incorrect. Last week I phoned again and spoke to another agent and was told it would be rectified on that day. Still nothing has happened. This is absolutely unacceptable. the money that was paid over is sitting in limbo somewhere and FNB have not allocated this to my loans that have been paid off!! I refuse to call and call again! This is ridiculous. I hope that this will get FNB to do something about this issue!
