In the past 3 months ordered different things from about 10 trusted vendors, 1 f them came and it was fucking BK-mdma so I was pissed off. Anyway if you keep not receiving mail to the same address would customs/police have a watch on that address for all inbound letters? And I've NEVER received a seizure letter for party drugs. does this mean it was never seized, just not sent...
You haven't given me much to go on but sounds like youve been scammed. Australians get scammed awfully because they like to brag about their customs officers abilities for some reason
However if you have had mail seized then border force could be keeping tabs on international mail sent to your address.
They do send letters for seizures of scheduled drugs (pharmaceuticals), not sure about illegal drugs (they dont differentiate between 'party' and 'real' drugs)
