Upset/Panorama test

Lauren
One of the main reasons I had this test done was to find out the gender early, obviously also to be informed of any abnormalities to gain knowledge for. 
Had the test done on Tuesday and they said 8-10 days before results would be back. I called today and they had the results that all tests came back negative (Praise the Lord!) but that there was an error message for the gender!! They said something to the effect of not having enough blood?!! I am soooo angry about it. What should I do?? Demand they do another test bc they messed up or just sit back and wait another looooong 8+ weeks???
