I set my email as spam, so I can't receive email reports.

If you are blacklisted, you cannot receive information reports.

Unless the other party cancels the setting.

If you often receive calls from this strange number and it is very frequent.

I suggest you use Tencent mobile phone housekeeper to intercept effectively.

It is very troublesome to use the interception function that comes with the mobile phone.

The effect is not very good.

You can try using Tencent mobile phone housekeeper.

Open Tencent Mobile Manager-Security Protection-Harassment Interception-Click "Interception" in the upper right corner-Add Blacklist-Done.

You can also intercept calls that hang up as soon as they ring.

I hope my answer can help you.
