Homechoice debits incorrect amounts from customers

I had the worst customer experience with homechoice. They've debit the wrong amount from my account for the past 3 months. I called for refund on the 22nd September, the rude call centre agent advised that she cannot process a refund immediately and I will have to wait for 10 days. I called again after 10 days and another agent told me to wait it is still being processed. when I called again on the 12th Oct a gentleman advised that the refund was never processed and that he will process it immediately it should reflect in my account in 48hrs. I'm still waiting till today, I spoke to Bridgette today who confirmed that the refund was processed today she put me on hold for 10min. I called again and spoke to amanda and she said I need to wait till monday. I cannot take another word from homechoice and want my money back in my account today. The service is pathetic!!!!
