I am reading this part of your post and it sounds like you did get a reply.
You said you "got some generic reply the first time, and responded" that you would like a reship.
Usually, if the source verifies you qualify for a reship (either you provided proof in your reply such as the seizure letter, or if they determine the tracking shows it is lost, they simply sends out the reship.
I don't think customer service always sends a follow-up email or reply (depends who handled it; some are just very busy, and working through processing as many inquiries as possible) -- they just mark the order status as "order lost" and authorize the reship; then, the computer system will generate the reship order for the warehouse to pack and ship.
If the reship has been processed, the order status will update from "order lost" to "order reshipped."
And, If reship tracking has been uploaded, it will show as additional tracking numbers on the lost order's status.
Please check your order status and verify if the reship has, or has not, already been processed:
If your order status is not yet listed as "order lost" or "order reshipped," do not worry, if you qualify for a reship, Basicstero will offer you a reship.
First, let me know what that status says; then, I can take it from there and write to my contact to try my best to help get you in communication with the source so this gets taken care of for you.
The source's customer service has been undermanned and way behind on a backlog of work (see posts quoted below).
It is my personal opinion that even at full staff capacity there is so much business that customer service staff are overwhelmed and working very long hours. This is not the customer service staff's fault -- I know they are working very hard (all day well into evenings); they have no control over how much staff is employed or if/when there are big increases in business.
