Disgusting service

I recently shared an experience on here about how Makro has not paid me my refund because they sent it to a closed account and refuse to make the payment to a new account. I have still not received any action on this. A recent refund for the same order was made two weeks ago and it was ALSO paid to the closed account, despite my communications with them. At the moment, they owe me almost R800. The same thing happened with Takealot and they sorted it out the same day. What could possibly be the issue with Makro? Their social media and customer service team is horrible and doesn't give any real response. What a horrible company.
