Used stamps exchanges.

There was nothing inside but an empty blank paper

l'enveloppe était elle fermée? peut être un vol? avant de sanctionner j'aurais demandé des explications, et sanction si pas de réponse.

You got an envelope opened by somebody?

No traces of damage on the envelop

I opened it myself

Jess, what stempels has the envelope on the both sides?
May be it's the custom's fault, depends on the country where this custom is.

I Would have first checked with Shukrat directly instead of this

If there was the option to remove my account, I would have done some while ago. Some pretty despicable people on here, who should rather go and buy their stuff on Ebay. Even got downgraded by a couple of people on my first exchange from a 3 to a 2 as they felt it justified because some one else graded it 2. I have pretty bad stamps, just so you know; but I won't bother sending them to you.
