Stranded after FNB don’t allocate funds to Euro account

I have a Euro account with FNB. Last night as an emergency I transferred money to that account as I needed to use it urgently. The money doesn’t show in my account because of a non-processing day. Airports and hotels don’t care about non-processing days. DO NOT open foreign currency accounts if you plan to top them up over weekends. You will be left stranded abroad in a predicament.
