I just paid (transferred) let's say 900€ (paper money) to my personal account. I came home to check if it was there online, and the number was let's say 9000€ larger. I though it was a digital mistake, but evidence of payment also says those 9000€ instead of 900€. Now, I am tempted to call bank and inform them but I would like to know if this happened to you or what are the outcomes in these situations? I know that this isn't a lottery and that I don't own that additional zero, but if I could rob someone, bank robbery by it's own mistake would be priceless lol.
