Query: BOYCOTT NEOMARK

The disk I received from Neomark through Amazon is faulty. It won't play on my Blu-Ray machine. It won't play on my computer. I'd never had a new disk that wouldn't play so I complained to Amazon. Amazon sent my complaint to Neomark. I didn't hear from the company. A few weeks later I again complained to Amazon. Again Amazon referred my complaint to Neomark. Again no response. So I complained again to Amazon. Amazon essentially stated that the problem is not theirs but is between me and Neomark. Obviously, I am disappointed with Amazon for not backing up a product sold through its website. As for Neomark, if the company even exists on planet Earth, I will never again buy another product from them. So I'm stuck with a bad disk that I have no choice but to trash. Now, I will always avoid buying products from outside sellers through Amazon. I could get burned again anytime. I suggest you consider my advice and do the same, especially with Neomark also known as Blackmark.
