Thanks for your help. Appreciate that. For package RS110862999CN, seller ask to wait because item in custom warehouse. Hmm I dont think so

1. Please don't let yourself fool, either ask him for a new tracking number or open a dispute to get your money back.

Hope this help.

Thanks. BTW , this package with tracking number RB009603670MY seems odd to me. Is it a real one

1. The tracking number is a valid tracking number. That number belongs to Post Malaysia.

Hope this help.
