I get calls on my business phone at least twice a day despite the fact that I am on a do not call list They are a disruption at my job. I have complained to no avail.
Keep records of the calls you receive. I have located the communications network with owns the number this number originates from even though it may not be 225 6015.
I have contacted the police in the crackpots area and made a complaint, Hopefully soon the idiot will end up as someones b**tch in a jail.
Keep calling idiot and you will end up in handcuffas
