Refusal to refund a double deduction

This is the 2nd time I complain about Nedbank double deducting on the bond amount and not giving it back. The first time was in June 2019, and now in March 2020 they have done it again.

My bond went through on the 24th, and again on the 30th. I have never missed a payment, instead I always pay extra when I have spare money. I called today and asked that my money be refunded, they deducted R 15 749.28 double. My other debit orders are now bouncing because I have insufficient money in my account, I have a 3 month old child and i am running out of electricity, NEDBANK is just not willing to assist with giving me back my money. I am gonna have to cover the expenses of the debit orders bouncing because of Nedbank that feels that they can come into my account as and when they want. This is the ****piest bank I have ever seen, both on a professional and personal level.

I now have to go to a branch, expose myself and my family to being in contact with people that might have corona virus, just because Nedbank refuses to give back my money.
