Tesla Model Y Juniper Duplicate Payment and Refund Complaint

I am requesting an immediate resolution to the ongoing issue with the payment for our Tesla Model Y Juniper. On September 22, 2026, when taking delivery of the vehicle, we accidentally paid 106,375.25 TRY as a single payment instead of choosing the 12-installment option. When we contacted Tesla, we were told that the single payment would be canceled, so we paid the same amount again using the correct 12-installment option. However, approximately 20 days have passed, and the original single payment has still not been refunded.

During this process, I contacted Tesla's Istanbul team through messaging and by calling 0 212 922 15 37. I have not been given a clear refund date, and I have received no concrete answer when asking when the money will be returned. Meanwhile, my bank has posted the single payment to my statement, meaning I have effectively paid the same amount twice, once as a single payment and again in 12 installments.

Although we genuinely enjoy our vehicle and were initially satisfied with the Tesla team's service, I am surprised and frustrated that such a straightforward refund has taken so long. This delay is causing me financial inconvenience. I request an immediate refund of the 106,375.25 TRY charged as a single payment, along with clear written confirmation of the refund status and a specific timeline for completion.
