Coach Overcharged But Still No Delivery

I'm writing to express my dissatisfaction with my recent shopping experience at Coach Turkey's online store. On April 19, 2024, I purchased an item from www.coachopturkey.com for $88.72.
After the purchase, my bank account was charged ₺3,033.92, which is significantly higher than the ₺2,890 listed on the website. This price discrepancy raises concerns about the company's financial transparency and honesty.
Furthermore, my order wasn't fulfilled completely. I haven't received the item I purchased, which reflects poor service and failure to meet advertised commitments.
I received an order confirmation and tracking number via email. My order number is #A24042000182287787, and the tracking number is EUBAM345007713CN.
I'm seeking assistance from the authorities to ensure this matter is resolved fairly and promptly, and that necessary steps are taken to protect consumer rights against the company.
I'm ready to provide additional information and details if needed. Thank you in advance for your cooperation and support on this matter.
I appreciate your understanding and attention to this issue.
Sincerely,
