I am getting multiple calls every day for the past few days.  Never leaves message

I Im getting calls from this number

I got a call from this unknown number 812-262-1578. I googled it and saw the comments listed above. Was not enough informaiton for me to tell who and why they were calling. I dialed the number and it says thank you for calling Reliant. We offer protection for your vehicle. I hung up ater that. I am not looking to purchase any alternate warranty or coverage for my vehicle.

They just called me offering an extended vehicle warranty.  The call was unsolicited and unwawnted, I don't know how they got my info.

Is this a slick repo service? How do they get our numbers?
