The phone rang, no message or talking

After a month of this number calling me twice a day they did talk. I normally just leave line open so they will be charged the call not me.
Told them they were a bloody nuisance and if they called againI would take Legal Action.
Hope it Works.

Possible scam. Hung up when I answered. I rang them back and it was Iko enegy. I was automatically placed on hold.
