Who called from 4165589982

Call received tonight, no message left. Called back and number is "Not in service". They are using spoofed CLID.

Every time I get a call from these people, they say they're calling for (from) Air (Ayr?) Duct Cleaning.  They won't tell me the name of the telemarketing company they work for, and despite having warned them several times that my number is on the NDNCL list, and asking them to remove me from their internal list, they still keep calling at least once a week.

So we report the call we received.  So what.  And that stops them how?

They call weekly.
I told them I will report this as abuse :)
They said, "But whyyy?"
Don't think they will stop calling .
