Requesting a refund from Takealot

I received an e-mail notification from Takealot stating that my order was cancelled as their supplier was out of stock. This e-mail further stated "Please let us know if you'd prefer a refund by replying to this email" (which I did). I then received an e-mail stating "We see you are trying to reach the team at ***. This is an auto-response letting you know that customer queries sent to this email address will no longer be rep**** to." This is a very poor showing from Takealot, especially as an online store where interactions with customers are primarily based on e-mails!
