Who is this moron who rings me up to five times a day and doesn't leave a message?

At first I would turn my phone offline for a couple of hours. But today (Sunday) I kept rejecting their call and they kept ringing back emmediately! This is harassment.

It seems to be a mobile phone, so they could have just sent me a text message or voicemail if it was something important.

I highly expect it's a telemarketer. Either wanting to sell me something or wanting my feedback.

When are they going to learn I am NOT INTERESTED!!

Don't call me, I'll call you.
