Who called from 4162053523

Received a call at 2:00 today.  No one answered an when I called back i got a busy signal. 416-205-3523
Is there still a "do not call" service as I get at least 2 BS calls every day and one duct cleaning call.  Those who do talk might as well not as their English is so bad I cannot understand them.

Duct cleaning. There's no controlling these guys. They just keep robo calling.

yes there is how effect another story I am calling police this idiot calls all  the time

blank callerid.  "Danny from duct cleaning services...".  i have requested politely, and not so politely, that they not call this number, but the calls just keep coming.

Called my house so often.  I didn't answer and then expected for voice message.  No message left.
