Who called from 4164215246

unwelcome calls have asked the individual to stop. Keeps on pretending like this is his first call.

These people call non stop bothering you eary daytime, late  evenings, weekends!!! Even after you tell them to STOP CALLING AND THAT YOUR NOT INTERESTED. They keep calling for months! I've been getting these calls now since June, 2015! And they are still calling till this day! I just received 3 calls right now from this number and all they did was listen then hang up...
This company (duct cleaners) should be STOPPED!!!

They keep calling from different numbers too.
Blocked IDs too. Calls from UAE, States, Switzerland.

I have the free app called Mr. Call. It works wonderfully on my Z10. Do not know what to do with home phone.

This caller been using different numbers and so persistent & no customer service manner. Demanding and annoying, always calling without leaving any messages but just unacceptable sound in the background.
