When they call us the ID shows as Vista Business 954 532 1655. They told us that a few years ago we purchased a travel package from Special T Travel and never took the travel and there is an additional about $600 payment due. If we do not pay Special T will charge the payment to our credit card on file. Special T Travel's web site that they do not do this and would not charge our card. We took the travel we paid Special T for. Vista Business does not have a web site. The BBB does not recognize Vista Business in Florida. When I called their numbe no one answered. We have repeatedly asked them to stop calling and they keep it up.
