Sunexpress Flight Meal Charge Not Refunded

During our journey to Paris on July 5th, the meal we purchased for our child was not provided because they claimed our name was not on the list. They even asked if we had a screenshot as proof of purchase. If we had known that you couldn't manage to provide a meal, we would have taken a screenshot, of course. They told us to fill out a form and assured us that once the complaint matched, the money would be refunded to our account. Now they are saying that the meal was delivered to us on the flight. It's like a joke. If the meal was supposedly delivered to us, then the cabin crew must have eaten it themselves. We had to buy chips for our child, which I would never normally allow, because the meal was not provided. They suggested we go to the Consumer Arbitration Board. As if we have nothing else to do but deal with issues you couldn't handle. Contact the cabin crew member named Y**** from the July 5th Paris flight and resolve this. Refund my money to my account as soon as possible. You will handle this, not us!
