EDIT: THE PACK HAS FINALLY ARRIVED (A WHOPPING 7 DAYS AFTER IT WAS SHIPPED!!!). I'VE BEEN ORDERING SINCE THE ORIGINAL DARKNET MARKET WHAT'S INTERESTING IS THAT I SINGED UP FOR TEXT AND E-MAIL ALERTS, AND THE PACK STARTED MOVING AGAIN THE VERY NEXT DAY. (for security I used a public wifi connection to enter tracking, as well as a phone number that's not mine and an anonymous e-mail address).
After signing up for these alerts, the pack started moving the very next day!!! Coincidence? Possibly but I'm leaning the other way because (from my research on web forums) the abundance of so many shippers claiming that signing up for text/e-mail updates on priority packs seems to consistently get a stuck pack moving again within 24-48 hours. Now of course if all of these shippers signed up for the alerts on a similar/same elapsed shipping day (meaning all of them did so after day___ after the pack was shipped) then one could argue that the pack was going to move anyway after that amount of elapsed shipping days regardless of signing up for alerts. BUT, this was not the case: between these different shippers/vendors, there was a large variety of elapsed shipping days before they singed up for alerts (meaning one shipper signed up after shipping day 5, another signed up after day 14, another singed up after day 25, etc. and all of said packs started moving again) So with elapsed shipping days all spread apart like that, and all of them showing pack-movement within a day or 2 of signing up for alerts convinces me that there is truth to that.
People who say that their packs started moving after calling or signing up for text alerts aren't thinking very clearly. Their packs just happened to start moving shortly after they did those things, because that's what their packs were going to do, anyway.
Any contact you make with them is not going to get your pack moving, and is going to kill any deniability. It's an obvious lose-lose thing to do. So don't.
