we really want to help and i can understand you very much, we are also very worry about the package, we don't want any dispute and return package on store, so we do our best to service each client.
we sent out the goods out around 20days ago, post office track it and it said it is under normal transport, means till now the package is no problem, your client may can not wait but please try to communicate with him/her about this. we still have some days before the end of giving time, i hope all go well and your client can get the package safety.
please let me know your idea.
