Hey KFC, PAY BACK MY MONEY!

I placed an order through the KFC app on 25th of December for the Walker drive store in PE. I was unaware that the store was closed. The order went through and payment was processed (R164.60). When I arrived, the store was closed. I contacted KFC customer care on the same day through Facebook messenger. Since then, it has been back and forth with them, where they ask for my details every two weeks, but I receive no communication from them. My refund has still not been processed, and it's been over a month since our first contact. Arrogant behavior. Horrible customer service!
