Evening Paul,

You ask where the faulty parts end up. As I alluded to in my first post, it takes a couple of months or so for the part to be tested and a refund made.

This tells me one of two things:

1) Part is put back on the shelf and if
comes back again , it is deemed as faulty.

2) If it takes 2 months or so, then I
reckon the delay is because they have so
many faulty parts to test

Regards
