want a refund please

I already confirmed the pregnancy and then took a Clearable advanced digital pregnancy test to see the "weeks along." I followed the instructions and put the tip in the urine for 20 seconds only, although that seemed like a really long time in my opinion. I ended up getting the error message and was really upset to have spent so much money on a test that didn't work even though I followed directions to a tee. The wrapper says CEN709/1 ADVANCED 2018-01 005 21:51 and the box says exp date 01 2018 Lot No.: 6131937237. I would like my money back or a coupon for another test.
