Called my cell phone at 5:45PM.  This is a scam outfit that says I stayed at one of their resorts and they are making offers for additonal stays at reduced prices.  When you call back a recording comes on "thanks for calling, the survey you are calling about........"    Just a scam, they use a different number every time they call so it does no good to block the call.  I have received this call many times from the different numbers.  Since the cell provider does not allow blocking very many numbers, it does no good to enter this number.  If they call your land line, go ahead and enter.
