Takealot using Covid as a reason for bad customer service.

I recently bought an item from Takealot and had to return it because it was not what I ordered. I then got a "do not reply" message stating that they would credit my account with the amount of the goods as they did not have stock to replace them. In trying to reply that this was unsatisfactory I found that there is no means upon which I can reach them as they are not manning their phones and the only avenue to communicate is through the website that does not allow for customer feedback.
