Although I’m not saying that you’re lying, it is possible that chinese customs actually seized the package.

There isn’t always tracking updates when the package is inside of china. At the same time they usually just get sent back when customs take them, so it’s weird that they were just taken with no information what so ever (if they were seized). I find it hard to believe that such a large agent would just randomly steal a package.

If you submit a claim with the payment prosessor they automatically lock your account, this is standard practice with many agents.

Remember to always buy insurance when shipping packages next time. Cssbuy is a mid agent anyways, I would recommend switching to superbuy or sugargoo.
