Unsafe online shopping with Woolworths

I am absolutely disgusted by woolworths. I made an online purchase on Saturday the 10/11/2018 for dinner for my family I waited for the order but no order arrived I called in the contact center numerous times and spoke to consultants who said they would call me back. I waited for more than 3 hours and no call back. I called the gateway store and sat on the line for more than an hour. My order was finally delivered on Sunday. On Monday morning woolworths *******ly debited my bank account for R148. I kept calling in to have this rectified and finally the contact center said they put in a request to have this reversed. Today morning I wake up to another unauthorised R720 that has gone of my account by woolworths. This is a breach of my fundamental consumer rights. And I have attempt calling the contact center and head office and all they do is say they will call me back.
