According to the BBB report the company has not even responded to several complaints made just like they have treated you and the other guy that posted a similar complaint
to the ZipZap Facebook page.

Makes you wonder how many people have been burned by them and said nothing?

They portray themselves as big time but act like a small time enterprise.  If they don't clean up their act they could go the way of Mt. GOX.  This is a defining moment for them.
