FNB ****** me

Good day

On the 27th of February 2019. I made a withdrawal on 475 usd from my trading account which is equivalent to R6731. FNB only proceed R4687. In them processing the money they looked for deposits i made before when Rand was strong against USD and reversed the transactions. Yesterday i confronted the broker and they send me a statement to prove they paid an amount i requested (475 USD) through FNB. They owe me a total of 110 usd. Rest on the remaining balance is not coming through. Today when i woke up i found a purchase of R1128. 00 its been #Items paid NO10 items 0. Mind you my card has been concelled from the 28th of February 2019 i never purchase anything of that amount. In fact my balance was R1 so it come as a shock to me. They did this before my other Cheque account is on a negative balance because they CAN. This bank is really unprofessional and their Cheque account serves as a trap to indebt us with no real reason. FNB should stop taking advantage of South Africans, we trying to make a living but the bank is still oppressing us. Please pay my money and also explain what i bought for R1128 whilst i have a balance of R1
