Considering Carolyn @ MSI gave someone £1,400 worth of laptop for free, for absolutely no reason, you should refuse to pay.
I agree with what he says .
why pay for a repair when its only meant to be an upgrade .. would you be paying MSI for repairs if it was "JUST" An "MXM" exchange into your faulty machine ? The answer would be "NO" you wouldn't so why on an upgraded laptop .
