FNB is ****

I use money gram regularly and it works completely fine with FNB and I am banking with FNB never had a problem before now I have been sent a money gram same details as always and I went to a ATM to deposit into my account as usual and it's not working, tried different ATMs still nothing. There is nothing wrong with Money Gram as I have contacted them. I have tried contacting FNB with this matter through my team of bankers and was told I need to go to Sandton to collect the money at the branch and then on the phone I was told nothing is wrong with my account and should be able to get it by the ATM so what's the problem? Clearly it's a FNB problem cause all is well with the money gram and I can't get a straight answer. Guess I will have to take my business elsewhere from now on and close my account with FNB as you clearly have no idea what you're doing
