Called did not speak and then hung up

Called me several times over the course of a year. I have never picked it up but, looked it up each time to find everyone saying the same thing - telemarketer or scam...

I missed the call, texted the number. No response.

They called me at 4am... I obviously didn't answer. I have txt it and no reply

They have called me numerous times, and each time I have stupidly answered but no one is ever on the other end. I never have called it back due to those scams.

it is in survey service called GMI, calling about the conditios in the province of British Columbia. Probably hired by the government of British Columbia. Checking to see if the peons are happy with how the political apparatchiks are wasting our money.
