X99 Extreme 4/3.1 - wrong firmware flashed

Umart have offered me AU$30 store credit.  Not sure whether to take it or not.  There is a  US$69 price difference between the two in Newegg, but Umart don't sell the older version, so can't compare the local price difference. 

Also, I did receive the USB3.1 card, which is worth something.  Plugging a Samsung T3 USB3.1 drive into it results in a BSOD every time, but that's a whole other issue, and probably not related to the mobo version (I think). 

 

I have emailed Umart and asked for a replacement mobo with matching serial number to the box it's supplied in (so I know it's new).

They've asked for the mobo back:

"For any other solution, we'll need to board back, as per our Service Centre request. We can certainly waive any labour charges as we need to find out how this happened."

Doesn't bother me how it happened - I'm only interested in verification that it did happen, so I can get a replacement.  I've offered to just take my PC in without dismantling it - in hindsight, it's pretty easy to see it's wrong without having to pull the mobo out.

If no dice there, it's on to consumer protection, which is unequivocal in Australia:

"A product or good has a major problem when it is significantly different from the sample or description.  You can ask for a replacement or refund if the problem with the product is major."

I'm hoping it will be all sorted amicably.
