We have received offers from this company via several sources. They will request your buyer's CP and TSA in order to have 'the refinery' approve them. They will reject most buyers without reason. When they do approve them you will be told the offer with good procedures and prices is sold and be switched to another. You will then be told they work with several refineries, so why the approval needed from THE refinery??
They are time wasters and despite asking for all of your information never reveal their so-called refinery. Don't bother with this group of information seekers who obviously have nothing to sell.
