I didn't recognize this number so didn't answer. The only thing I could find out about them online is a post made from some one in Florida in 2010 saying that this is a message from BP Gaslines calling because the poster had requested underground utilities to be marked in their yard prior to digging.

I'm in Michigan and this call is supposedly from Oklahoma.  I've also requested my utility lines to be marked as I'm preparing to do some work.  In MI, we call Miss Dig at 800-224-7552, so I wasn't expecting a call from an unfamiliar number.

If this is legit, I hope they call back! lol
