I have told these people I am on the no call list and don't want them to call again..they seem to persist.

Caller ID just said "SECURITY."  Received a call from David Gilmour from OS Technologies.  I told him I was so excited to get a call from him because Pink Floyd is my all time favorite band and I love his guitar work.  Then I said that I didn't know why he wasn't speaking with an English accent.  He claimed he would have an alarm system consultant in the area tomorrow, told him I wasn't interested and he concluded the call.

OS Technologies has a website which gives their business as being in Vancouver, WA, but the 971-302-7280 number is from Portland, OR.  Possibly a hired call center.  Don't know if this company is legit or not, but I'm blocking their number anyway, even if David Gilmour is working for them.
