They want you to call that number back and then that way they have access to your info and charge up your bill. I saw a news report on this, where you will get calls from a strange number and then when you call it back they charge your account hundreds even thousands. Do no talk to them, do not answer them, I keep declining the call everytime. Eventually they stop and then yes a few weeks later start again. But I dont care, anytime I get a call from a strange number it is ignored. At night I put my phone on silent because this way if they decided to wake me up in the middle of the night in hopes I will be more compliant in my sleep they will still get a voicemail.
