Unproffessional

I have been under debt review but stopped it recently as it was no help to me. I made payment arrangements with FNB for a lower installment and could not meet it as my husband lost his job leaving me to be the obly breadwinner in the house. FNB handed me over to Brooks and Luyt attorneys to make other payment arrangements. I am still in the process of negotiations as I gave them the amount that I could commit to paying every month. I still have not heard from them. Now FNB deducted an amount of R3570 from my account without informing me prior or getting my consent. I want my money paid back onto my account.
