Burger King Won't Give Me My Money Back

On the evening of June 22nd, we ordered from Arastapark Burger King branch via Trendyol GO food. When our order arrived, one of the menus was missing a hamburger, we had bought nuggets, but it was missing. There were no extra sauces, not even the menu side sauces, let alone the extra sauces. In the hamburgers that came, the papers were torn and scattered as if they were thrown into the garbage. The onion rings are stale like ice, the only thing that is right and beautiful is the coke they send. I created a return request, the response from the company was rejected, I created a return request again, again rejected, I created a return request 3 times and I am waiting for an answer. Let's get the payment in advance, let's send the product incomplete, I guess they think that the return process is up to us anyway. So much so that the receipt of another order came out of my order. And there is never any interest. If it is rejected this time too, I will seek my rights through legal means.
