Hello! This my order (RP853496274CN) has arrived in Beijing from Guangzhou and now it's back again to Guangzhou, is everything ok with this package? Thank you!

Hello, want to ask can I get a confirmation from you. that this package was sent with economic method within China Post, need this for dispute on one site for sale. The package was tracked in country of buyer by local post maybe by mistake, or because the package is was a little bigger, I think that this second is a reason, so that's a problem. Package was ordered with China Post Registered Air Mail but the seller is sent with Small Packet BY AIR. Package number: RP853496274CN
Thank you very much!
