WePlay SMS Verification Code Not Received - Phone Binding Issue

I have been unable to bind my Samsung phone number to my WePlay account for about one week. I already have a WePlay account on Android, but when I try to link it with my Samsung phone number, I do not receive the required SMS verification code. The screen shows that a 4‑digit code has been sent to my number, but no message ever arrives, so I cannot complete the phone number verification process or bind the Samsung phone to my account. During this period I have repeatedly tried to request the code and have checked my phone and network, but the SMS still does not come. I also contacted WePlay support, but I have not received any response so far, and my issue remains unresolved. I request that my Samsung phone number be verified and linked properly to my existing WePlay account as soon as possible or that you provide an alternative manual verification method so I can use my account without restrictions. I also expect a clear explanation for why the SMS codes are not being delivered and for this issue to be permanently fixed.
