Regardless of what they offer, as I have previously stated you have far more rights under the sales of goods act.
Yeah in hindsight I should have sent it to OcUK under the Sales of Goods Act but I wasn't aware the problem was caused by missing pins (it just wouldn't start up and I didn't check the pins) so I assumed OcUK wouldn't have a problem replacing it. When it was returned to me at cost I became reluctant to send it back to OcUK in case of another rejection and more cost, so took the hassle-free way out.
