Who called from 4162333550

I only see this number on my phone when I get home from work. No message, no ID (tried a reverse search on www.canada411.ca).

Same guys called me twice, wanted to ask me about customer service experience with RBC. I guess they do marketing research for other companies as well...

-file a formal complaint with crts and consumer business bureau
-buy a copper whistle (about 4 inches long) and blow your whistle as loud as you can when they call you next time; the pierce sound will kill their hearing
-this is what i did last time and since then, they never called me back
