Business Doesn't Seem Trustworthy

I paid for a table with 2 EFT payments. First payment was a deposit. When I was enquiring about the table, Pinky wasn't responding much. I had a gut feeling not to make the second payment but I ignored it. After I made the second payment which was the full amount, Pinky informed that there was a burst water pipe which damaged furniture & my table was one of the items. I asked for a refund. I was told that they don't do cash refunds. I had to send a PDF document with my bank details. I was told to wait 7 days for my refund. Since the 11 of February, I have not received my refund. I have been liaising with Pinky via WhatsApp. When I try to call the store, the number cuts off. This sounds to me like a ***** business. I need to purchase another table but I am unable to due to the fact that my money is held up by Discount Decor. Why must I wait for 7 days to receive my money due to a problem that happened at the store? By the time I get my refund, the table which I need to buy might be sold so it will be the second time that I won't be able to get a table that I like. I think that this is not right as per the Consumer Act.
