FNB do not care about their customer. Disgraceful service

I have had an absolute night mare with FNB. Mistakenly I paid money into a wrong account and have asked for a reversal on the funds. This has now been going on for weeks. Standard Bank say that the reversal has to be initiated by FNB and FNB say stb is responsible. We have banked with FNB for years having 2 Buisness accounts with them and 2 personal accounts with them , they are happy to take your money but are discusting with offering any help. Standard Bank staff were much more helpful even though I don’t bank with them. Think it’s time to change banks. FNB service is terrible
