BAD SERVICE FROM ZANDO

I had the worst online shopping experience with Zando. I made an order on 20 November of R949. After paying the amount with the debit card method I received an email from Zando saying that the order was cancelled because the payment was unsuccessful. Although the money was out of my account. I immediately called them to explain this and they said they reversed the money back into my account and I should receive it within 3 days. 3 days later, the money was still not in my account. I called them again and they now said it would take 7- 10 working days, I patiently waited and called them after 10 working days because the money was still not back in my account. 20 days later, the money is still not in my account. I have been calling them and their limes are not being answered. They are also not responding to any of the emails I've sent.
