Here are general steps you can take:
Contact your service provider: Reach out to your phone carrier's customer support and explain the situation. Provide them with the specific phone number that is being flagged as spam, and ask if they can review and potentially remove the spam designation.
User feedback: Some spam detection systems take user feedback into account. If your phone has an option to mark a call as "Not Spam" or similar, use it. This feedback may contribute to the improvement of the spam detection algorithm.
Check your phone settings: Some smartphones allow you to manage and customize call blocking and spam detection settings. Look for such options in your phone's settings app and adjust them as needed.
Remember to exercise caution and verify the legitimacy of the calls before taking any action. Scammers often use tactics to make their calls appear genuine, so it's crucial to be vigilant when dealing with unknown numbers.
