Finaly got my answer today after having to mail them again about it and one week of waiting for response( probably went through MI6).
"Thank you for your email regarding What Hi-FI Magazine.
We have just taken over handling of the subscription from the previous subscriptions agency.
Unfortunately we do no have any more stock at present of the powercables,
it looks like the free gift you received was a alternative for this product."
Now, I just wonder how many cables you had in stock as gifts or how many people did subscribe before me, did it first day when offer went live @ 8am.
