Takealot is *****ing our money - cancel orders and not refunding

Takealot is taking peoples money and cancelling orders due to lockdown. How is this legal? I asked whether they cant just put the order on hold until after the lockdown and got a response that it needs to be placed again. So they are keeping my money, not willing to refund it, which has been paid on 22 March already (over R1000) and I must just hope that the items are not more expensive when I want to place the order again. If they cant keep the order on hold and want to cancel, they should refund the money!!! Very upset about how they are dealing with this.
