Dishonest business practices

I had a car insurance with the company. I called them to inform about the car being involved in a car accident, and the car was written off. And IWyZe said they would pay me some of your premiums back and stop debit my account. However they are still debiting and I have not received my refund of my premiums. Disgusting business practice and disappointing customer service because I call and I don’t get assistance.
