Bad service

Good day. This is the second time this is happening to me last year also and I know for sure the bank will say I have received it just like the previous agent that reply with in 2 second. I do help someone selling stuff so as ppl pay I transfer the funds to my savings as soon as the money is there. An amount of 480 was paid but C duploy.i haven't received the money and I don't lie. it does reflect there but I swear I have not received the money. I had to take a 400 from payment made by Sandy as I will be short on the funds I received but I do swear I have not received as I didn't transfer anything . this is for this month. A Yasmin also made a payment of 240 but when I got money only 220 I could have transferred but it shows she paid 240. If the bank is going to make me a lier and said I did receive I am closing my fnb account
