Takealot and my Non existent Credit

I am appalled at the service and lack of communication. I purchased a R1000 sandal from Takealot for my father, the day it arrived it didn't fit so we requested a bigger size (which was available on the site)

After a day, it read "RETURN CONCLUDED, ACCOUNT CREDITED" firstly, the account was not credited and secondly they claimed that the item size we now require is not available (but it was) The consultants work until 10pm, I called from 7pm and was put on hold for 18 minutes. No answer. Then an automated message kicks in at 7pm saying: "Our consultants are working from home". I think this is riduclous, so of course the account is still not credited with the R1000 and they are not answering social media, emails or calls.

At the very least I expected the takealot acccount to read a credit of R1000- but no. The latest communication was on twitter where they claim someone will be in-touch and that they are experiencing high call volumes and queries. I mean, really?
