Trendyol Laser Hair Removal Refund Delay

I purchased a laser hair removal device. It was clear as day that the packaging had been tampered with and there were smudges on the cover of the product. After giving it a try, even though we had the exact same product with identical specifications, it didn't quite match our skin tone and didn't work as expected. As a result, we decided to place another order. Due to apparent damage during shipping, we decided to return the product. It's been a month since we submitted our refund request, and now that our flight is about to depart from Turkey, we've vacated our residence. We are still waiting for our refund request to be processed. At first, we patiently awaited a product exchange. We've reached out to Trendyol multiple times, and they explained that it's part of their standard product inspection process. Now, we would like a refund as we no longer wish to keep the product. What comes after this? What steps can we take to ensure we obtain our rights? We're departing for our journey in just two days. We have decided to discontinue our use of the product. We kindly request a prompt refund of our funds.
