I have been receiving harassing phonecalls for the past several months from a blocked number that reads "UNKNOWN" on my phone. I have suspicions about who is calling me but I want to be sure. They call everyday, and sometimes they call multiple times a day. If I don't answer, they leave me rude and inappropriate voicemails. Is there any way possible to trace the phonecall or unblock the number?

Report this to your service provider.
They have tools for this kind of thing.

It isn't possible for you to do it so get help.

Yup, Curlyben is right.
I think all you can do is call your service provider and tell them your problem.

Because I had an issue similar to this a while back, and I called Rogers, and they said that if the conversation is nothing serious or like harassing? Then they can't give you the number that's calling you. But they did issue me a credit so that I could change my phone number w/o having the pay the admin. Fees.

If your situation is getting more serious, then you should call the cops.
