got 5 calls today from this number and do not know anyone with thisnumberf

I received a call from this number (780) 702-7489 this morning on my cell and answered, heard the accent, sounded like a guy from India, and I hung up right away.

I received a phone call from this (780) 702-7489 and there is nobody there.  Is this a scammer
number?  I also receive lots of unavailable numbers with nobody responding, I wait and then they
finally hang up.

This number comes up on my caller id every day I don't know who it is

I just got this call on May 21 at 16:39, the company name showed as Cres-tech with the number of 1-(780) 702-7489, I did not answer and they did not leave a message, so who knows who they are!

I recieved two calls and I was busy. Later, I call back and no body answer me. This is very estrangeandfor sure, no so nice.
