Who called from 2049461829

Received calls on call display.  Call the number and voice message, woman, says don't leave message?

Getting a call at least once a day from this number for the past week or so. Never leaves a message.

I also have gotten calls all week, no message. I answered it once and no one said anything. Callback message sounds like "San Diego, do not leave message"

It is a call centre that calls on behalf of a number of organizations.

I received a call from this number today asking me to book a service appointment with a car dealership.

Got 2 calls from this number today.  Caller ID says Manitoba.
