Wesbank don't stick to agreements

So Wesbank is taking money out of my account left right and centre, they taking double instalments on both my vehicles and bike and out account has never been arrears with them! We signed debicheck debit orders for security reasons but now they taking money as they please. I have all my statements showing that my vehicles and bike is up to date and now this ****! This is now caused that I don't have money left in my account to buy for my house bond that is also due to go off via debit order! This is now affecting my credit record because you people ***** money from a person's account! You will rectify this and reimburse me for all my money even the penalty fees as well as rectifying my credit record because of you my bond bounced! Who gave you authorisation to double debit my stuff!!!!!!! I contacted your secure chat and I was told they can't help me I should call Tuesday!!!! Pathetic service quick to take money and they don't stick to their agreements with clients!
