constructiondeal.com credit is not a good thing? Internet

Constructiondeal.com promised me that their company would provide me with qualified leads for my business.  I received 6 leads and got charged $239 for them.  Every one of those leads were bogus. I did not even get the opportunity to quote any one.  Either they were not interested or, they did not even know why I contacted them.  It was like they got them off a random list.  When I called to complain, they were unwilling to grant a refund, only give me a credit.  What good is a credit, if All their leads are crap.  Again, they assured me that their leads were bona fide, unlike their competition.
