Nedbank *****s money from account

Can Nedbank tell me why it is that EVERY SINGLE MORNING I WAKE UP AND THERE ARE MULTIPLE R10 BEING CHARGED ON MY ACCOUNT. I HAVE NOT USED THIS ACCOUNT since the 8th of October because I realise that my money disappears every single day that is close to R40 R50 missing on a daily basis and when I called I was told that it is because of transactions that have declined but actually it’s not the case I have not used that card since the 8th of October yet there are all these 10 words that are wanting to R70 that go off my account every single time now my account is on a minus because what I decided to do us to move my money from your bank to a different bank because I am tired of losing money every day R70 may feel like a small amount to you but it’s a bigger amount to me as a single mom
