Problem with Planet Micro

I would just like to share my experience with Planet Micro.

I ordered a Diamondmax 9 HDD and a Sony DDU1621 DVD rom as clearly described
in their online product description. When the delivery arrived I received a
refurbished Diamondmax 10 (the 10 has a different power connector to the 9)
and a Sony DDU1615. When I brought this to their attention they seemed
fairly disinterested and gave me an RMA to return them. They received the
returned goods a week ago and they still say it is going to take another 7
to 10 days to credit my card!

Is it me or is this unacceptable?
