Cam Problem!

I had comp cams cam go flat me also. I do the break in the same way every time. I use comp cams break in lube on the lobes,and oil-stp on the bearing surfaces. When i called comp about the cam they gave every excuss in the book but they warrentied the cam. They were very quick at replacing the cam for me. I flushed the system, new oil filter, oil and did the same thing i did the first time. I had no problems this time. changed oil and filter after break in and again at 600 miles. that 3 oil changes and 15000 miles ago. I think it was a bad camshaft first time around.
