Hi I ordered a package a little while ago and it has been stuck in collection for a while. The number is RB594849432CN

I check every day and it always said collection. That must mean that they recieved my package. But no further information has been included. Please tell me when my package will arrive. It shipped Thursday the 25th of July can anyone tell me an estimate of when it will come. It is coming via china post. Please tell my how my package will arrive and where it will reach before it reaches me if you can also please tell me when it will arrive thanks
