Can’t say about the problem. Contact to 360 Security support. They will definitely help you.
Did you try to add your country code before the number eg.. +1, +91. etc. because when you receive the call it comes with country code, if you have not added country code then it will be not blocked by 360 Security.
I have a number that keeps calling me. I have blocked it several times, but they call even after I block it. It’s the same number. And it’s like it can’t be blocked. Is there anything I can do to stop them? It seems all other numbers are being blocked by 360 security.
