Query: Capsules one third empty.

I purchased this product based on the glowing reviews from many other users. I just received my order yesterday and I am extremely disappointed. I took out the first two pills and noticed they were a little empty at the top of the capsule, which was weird. I poured the rest of the capsules out and ALL of them are are filled to about 2/3 of the capsule. I've never seen anything like it and I'm wondering if the reason it's such a low price is because the company is actually not giving your 240 capsules of product but instead making up the price difference with empty space. I've sent an email to amazon asking for an explanation, we'll see what happens.
