Cobra Bio Cell+ FW

Early this year, I bought two Cobra Bio Cell+ Fairway woods (3 & 5) from Golf Direct.

They were very nice and I enjoyed it.  My balls were flying where they should be, most of the time.  I was getting good distance.

However, about 5 months into it, after I tee'd off on a Par 3 (170M), the 5W head flew off!  I didn't hit the ground, etc.  The ball even got on the greens!  It was a good tee off!  

Since GD had a promotion where it was buy one free one... I didn't think too much of it.  

The next month, as I was packing my golf bag for a trip, I realized that the 3W has a crack and one touch, it broke off!  

Now, I have two broken Cobra Bio Cell+ FWs sitting at home.  I brought them to GD Ubi but they won't do anything until I gave them my receipt  or even a credit card slip (which I've thrown or misplaced or maybe I bought with cash).  

Can anyone tell me who to talk to get a replacement or even better, refund?  GD won't do anything without any records even though they can scan the barcode on the shaft and know that it's theirs.  

Thanks!
