I got a phone call from another number tonight, and it was someone wanting to buy our timeshare.  My husband answered it and ended up getting transferred to this number at a company called ICMG.  They were VERY high pressure, wanted us to commit to having them sell it.  They wouldn't even give us one day to review the contract.  Then they wanted to know what type of credit card that we had...  and later in the call wanted to know the last 4 numbers of the card to "verify" identity.  I grabbed the phone and hung up at that point.
