Called.  No one there when I answered.  I was out of town but live in Ohio so I picked-up.  Now blocked

I think this is a robocall to see if it is an active number.  First time I received a call, no message.  About 2 hours later I got a call for an "Auto Warranty"  I am sure one number is feeding the other.  Both blocked now and I have been called 3 times since the block.
