Allright ! That explaines a lot , thanks man.
I have bought hundreds of times of the internet but this has never happened to me before. Fortunately my order at QTH is for a small amount of money , so no real harm done I guess.
I will bury my hope of ever receiving my order. The amount was about 25$ so I won't bother going true the hassle and paperwork involved to get the money back from VISA.

Thx again for your help.
David.
