Unwanted Bigo Live Notifications Sent Without Account or Subscription

After my spouse purchased a new Poco X7 smartphone, I began receiving constant notification messages from Bigo Live starting yesterday. Even though I deleted the app from my phone and have never created an account, the messages continue to arrive.

I have never clicked on any links in these messages or performed any actions related to the app. My mobile line is registered with Turkcell.

I do not want to keep receiving messages from an app I do not use. I request that these unwanted notifications be stopped completely and that my phone number be permanently removed from the Bigo Live system.

This is a serious violation of user privacy, and I expect the issue to be resolved immediately.
