Poor customer service response

I received an air fryer as a gift. We unpacked the item, wiped the inside down with a cloth, as we were going to use it, and I then noted the size was too small. We boxed it back up and returned it for a credit, so I could purchase the XL size. The return was rejected due to "WIPE MARKS". When contacting Takealot I was advise that the item has "WIPE MARKS" so must have been used. I advised the consultant what we had done and was told they would review the return. This never happened. Takealot advised they would contact me via phone on Friday 1 July, again this never happened. Sent more emails and I am now being ignored. The company does not have phone numbers so you are stuck with an email address they just ignore.
