I went to deposit money for my sister and I sent her the reference number and the pin. The following day she went to withdraw the money only to find out the money was withdrawn the previous day, 5 min after I left the store next to the complex I deposited money to. What I dnt understand is that how did however withdrawn my money saw my reference number n my pin because I didn’t give it to anyone but my sister. My sister is in another town but the money was withdrawn at the same town as me
