Minersource recently screwed me over too on faulty equipment.

I picked it up from their local guy "Matt", he said to call if there were any problems... Well there were, one was DOA and the other had major performance problems. Well "Matt", decided to ignore my calls after that. I can only conclude that they knew the equipment was bad and had no intention of making it right.

After that I contacted them by email, got a response from Dan Murtha basically saying tough shit. They ignored several other emails after that.

Even if they weren't hurt by Black Arrow, they've proven to be a badly run business with poor customer service, I won't buy from them again.
