Query: These are horrible!!!!

I purchased a spool of these last month and have had nothing but problems. The top 3 on the spool wouldn't even register as "blank media" in my burner. I tried to return them, but was told (retailer issue) that they don't return opened blank media (floppies, vhs, cassette, cdrs,) etc. I emailed the company and decided to try one out of the middle of the spool. Success! It worked. However, 20 discs later, I have had about 7 that have turned out badly; basically static that makes the music unlistenable. I tried it on different players with the same result (and I'm burning @ 2x). I tried a different brand (smart and friendly) and had no problems. In regards to the customer service, I was just told (also) to try one from the middle of the spool and/or try different cd burner software. I kept up this communication with them for over a week, and they never once offered to either replace them or refund my money. I WILL NEVER BUY THESE AGAIN!
