ATTENTION IZWE LOANS- UNAUTHORIZED DEBIT ORDER

My mother had a loan with them and unfortunately lost her job.She was handed over to their lawyers (GvDM Attorneys) and made a payment agreement with the attorneys to pay R200 per month which she has never failed to do for the last year and few months. Yesterday her bank sent her a notification that Rite Credit (Izwe Loans) made a debit order on her account. She fortunately had no money in it and it was reversed, but now she will have to pay such fees as well. I send her money on a monthly basis and the fine cheek they have to debit the whole amount (Don't know how they know the amount of money her account has in it every month). It is unauthorized because she never gave any consent for it. When she made the loan she opted out to pay them via atm/branch or eft every month she never agreed to a debit order on her account. What I want to know is why should she pay them as she no longer has an account with Izwe Loans as they handed her over to the attorneys?And why should she pay two different places? I would like Izwe Loans to please explain to me what is happening and would like them to cancel the debit order immediately. My mother is in a frantic state because if they debit the money I sent her every month she will be left without a sent. I am pleading to Izwe Loans to please sort this out. You can contact me on ********** should you need my mothers details I am more than happy to forward it to you privately. Thank you
