Angry customer

I ordered from the fin Kenilworth on the Mr delivery app and received a message saying they could not reach the store so I made another order and again received a message saying the store was not reached I decided not to order. I realize later that they made 2 deductions for both attempted orders and have not refunded me. It is a whole day later and they still have not refunded me. I'm upset and disappointed as I've queried the matter but have not even received confirmation of my query
