Temp loan

I don’t understand how fnb can give a temp loan then take half of that loan within a week. When i call them they tell me because i had transferred money from “bank your change” facility. Firstly it is fnb that automatically took that loan money into “bank your change”, i only retrieved it back into my account so i could use it and now they took the very same loan before I could even use it. Very pathetic indeed. Clearly your system don’t speak to each other
