Yes nice to have it sorted out.
But he should think himself very lucky he didnt get charged carriage for at least some of the journeys as this wasnt Scans fault at all, surely common sense would show up a 4 pin lead and a 4 pin socket, and think "i wonder do i put that in there?" and check it out, especially when things arent working before raising RMA and couriering stuff about?!!!!!
Anyway, older and wiser now!
