Tks for the answer, i did quite a bit of research and the guy seemed to be good (just slow with the mailing). I will wait a few more days and send a ticket to the alphabay staff, unfortunately it was a FE (i know this is a no no most o the time and maybe it was a mistake of my part)
Vendors are people with regular lives too. So it is totally normal for them to take breaks. Maybe you could cancel your order and go with someone else? And you should ALWAYS research a selected vendor BEFORE you pull the trigger.
