We didn't answer the call but found out the number on our caller ID and it said Express Oil Change. My wife had her car serviced at one in Florida yesterday. I dialed it within 2 minutes - it went either into a ring tone (music) or on hold with music background.
googled it and it's Express Oil Change HQ in Birmingham, AL. I just had some work done there a couple of days ago so assume they are checking customer satisfaction.
