Back in March I ordered a bunch of pills for personal consumption from Megapharma and Tbone at the same time. Tbones package came and Mega's never arrived. Mega however provided tracking # and to this day it still says in customs over a month and a half later.. He stopped responding to my messages. His "100% ship rate to USA" is now BS.. Just noticed he ships more than just pills. He hasn't offered a reship or refund like in his profile. Fucking scammers and Auto finalizations. Avoid this dude like the plague.
Well - I would place doubt on the credibility of "100% success rate to the USA through customs". however, I have dealt with the customs limbo you are in - I know it's friggin torturous, to see it never move - but I think the USPS has cut back on staff so much, or so they say, that a 6-12 weeks delay is not at all unheard of.
I ordered something legit (not DarkNet) and it took 10 weeks to reach me. Within that time, I reached out to the seller, having the same thoughts as you - well their second package shipped sailed through and arrived in about a week... then I got the original package, too.
And yes, even though I had nothing technically holding me back from not paying for the second shipment, I paid for it anyway
Your story reminds of why I only order domestic from DarkNets, with the exception of ONE vendor who I knows for a fact uses a non-USPS carrier
