FNB just do not care

I was sent money from Italy on 7 February 2018. After sending several E mails, and visited the bank 6 times - they still can not find the funds. they do not even get back to me. The Italian Bank has sent them all the information - they have gone to see and the money is in SA, but FNB is not very interested to even go into the case to see here the money is. I have gone to the other banks, they all say the same thing the money has gone into my bank account - FNB just say there is no money. So now the Italian bank is saying that FNB must have ****** the money because the money should be in my account. I have always been the biggest FNB fan - now I have to swallow all my words and now it seems they just do not care.
