Trendyol SMS Verification Not Working (+966): No OTP Received

I have been facing an issue with the Trendyol main shopping app for more than two weeks. When I try to log in or verify my account using my phone number with the country code +966 in Riyadh, the application shows the message “verification code sent”, but I never receive any SMS code. I have tried every possible solution from my side. I contacted my mobile operator, and they confirmed that there is no problem on their side and that there is no block on verification messages. I tried logging in from the browser instead of the app, but the code still did not arrive. I even changed my mobile operator to another company and the problem continued in the same way. I put my number in another device and the verification SMS did not arrive there either. I removed all blocked numbers from my phone, and I deleted the Trendyol app and reinstalled and updated it, but nothing changed and I still do not receive any verification SMS from Trendyol. I kindly request that this issue be escalated to the technical team to check your SMS sending system and to verify whether there is any technical issue or internal block on my phone number in your system. I expect Trendyol to urgently fix the SMS problem for my number or to provide me with an alternative verification method so that I can access my account again as soon as possible.
