I had the same thing happen with a card company. (Extremely expensive hand made cards). I loved their cards and was tickled to get the position, filled out tons of paperwork, got locations, waited for contact by trainer... waited....waited.... finally gave up.
Have you called the phone number on their web site? It is right on the first page. I never give out sensitive information when someone calls me out of the blue. I ask their name and tell them I will call them back in a few minutes- I just got out of the shower, need to answer the door, my hair is on fire, the swat team is outside , any excuse to not give them the info then. I then look up the company on line or white pages and call and ask for that person. I don't have caller ID, but if they give me a call back number I will reverse look up them. I have noticed there is several of the MS site which are listing scams which are using their names. Kind of scary. Hope you get some closure on this, it is always a PITB waiting.
