I've not done business with this company ever and I am on the do not call list for my cell phone. When I tried to call the number back it just gives a very fast busy signal and you can never get through.
They are a marketer of a sports book or some sports gambling/picking service. Just hang up unless you want to gamble with someone you don't know or trust someone to pick your games that you don't know.
This number has called me quite a few times. It is a recording selling some sort of sports package, so there's no way to request I be removed from call list. I would appreciate being removed from call list as I am not interested in anything they are selling!
