REFUSAL TO CANCEL AN ORDER

I bought Palladium boots online and submitted a request to cancel the order on the 18th April only to get a response 10 days later being advised that they cannot cancel the order due to lockdown restrictions. So they are able to process orders online yet cannot cancel them. I have asked for them to refund my money and they are refusing to refund me. I have not received the boot so i cannot understand why they cant cancel the transaction and do an EFT. If maybe they are under the impression that I do not understand the consumer protection act than they better think twice. I WANT MY MONEY BACK, I am never buying anything from that company.
