Left nothing on the answering machine.

I got a call about a month ago, it was the only verbal call I got. I didn't persue the call since it didn't look right. I tried the BBB but I didn't have a city to report only the phone number. I was just wondering if anyone else decided to go with it.

I have a contract from them but can't get them to return a phone call

Wants to buy my house??? Sounded Fishy.......
