I Did Not Receive My Bonus From the Campaign

Dear Garanti BBVA, I am writing to inform you that I participated in your campaign titled “Earn ₺2,000 Bonus for Spending ₺750 or More with Your Bonus Credit Card,” which was valid until July 31. I fulfilled all the campaign requirements and completed the necessary spending as outlined, yet I have not received the promised ₺2,000 bonus, nor is there any indication of it in my account. I kindly request that the bank honor its commitment and ensure the bonus is credited to my account as promised. Thank you for your attention to this matter. Sincerely, Zeynel.
