Masterpass Payment Fails on Yemeksepeti Due to Phone Mismatch Glitch

When I try to pay on Yemeksepeti using my Yapı Kredi World Gold Troy card via Masterpass with the phone number registered to my Yemeksepeti account, I receive an on-screen error stating, "The phone number in your Yemeksepeti account does not match the phone number in your linked Masterpass account," and the payment fails. Despite multiple attempts, the exact same warning appears every time.

However, the phone number on both my Yemeksepeti account and my Masterpass account is identical. I deleted and re-added my card on Masterpass, verified my phone number, received a verification code, and am completely certain that all my information matches. Despite this, the system still refuses payments and prompts me to "Contact Masterpass."

Because of this issue, I am unable to process payments on Yemeksepeti or use the service. I request an investigation into why I am receiving this error despite having matching phone numbers, alongside necessary technical checks and fixes to resolve the issue as soon as possible so I can complete payments via Masterpass.
