@springy - it's often true that you need to upload it into the case, even if it was entered into the transaction.

Perhaps the OP didn't upload the tracking originally? Or maybe they didn't send within their handling time?

The OP hasn't clarified the value of the parcel and since he has some VERY expensive stuff, I think maybe he didn't send with SOD, which is why the unscrupulous buyer is taking advantage.

OP will hopefully come back to give more info.
