I am a subscriber of LFY and my experience with CD/DVD is also the same 30% to 40% of the time I get faulty CD/DVD's but hey are good enough to replace them though it make take upto 10 days.I have also communicated this to LFY to improve upon their CD quality but i guess what you said is right untill and unless there is a mass level complaint nothing seems to work.
