Are you guys serious? Let it be user's mistake or manufacture fault, a company HAS to have a responsive customer support department. No response = shitty customer service = enough reason not to buy from them again. No one is asking for free replacement.
I've been struggling with Logitech for my 150$ mouse's broken battery cover, left with a response stating that they don't have/sell these covers and there's nothing to do except giving me a %50 discount coupon just to satisfy me. I got the response in 24 hrs. Even though I'm unable to buy a replacement part from them, I'd still buy something else any day for their excellent customer support. Finding some other solution is your creativity but not having answer from a customer support is something else.
