Your post makes no sense. Why would the post office refuse to deliver a package? And which time did they give a second number to cancel what order? Also, there IS no necklace or any other 'free' gift. They're trying to rip you off by having you give them a credit card number.
This number appears on a card mailed from Hong Kong stating that there is money which I can claim by phoning (no charge for this call). Fat chance of that, since I don't live in that area code. S.C.A.M.
