I went to First Bank ATM to make withdrawal i selected 10,000 out of the available options,unknowingly i collected the money i put it in my back only for me to received a call on Saturday which is a day after from First Bank staff that i was over paid by their ATM i argue at first instant then i asked the caller to wait let me count the money since i have not spent from it yet behold it was 20k instead of 10k has this ever happen to any body? Honestly speaking anything is possible no doubt about this.
