Nine days is the standard speed of this garbage logistics. My things arrived in eight days, and I bought a mobile phone t800, but I complained on the seventh day. I logged in-(left) complained and arrived the next day. However, I also said that it was not a complaint and it was handled uniformly, but it was indeed given to me after the complaint was finished. This is my practical experience, I hope to adopt it!
If it doesn't arrive, as far as I know, it is difficult to change logistics. It's because when I wanted to change logistics, I was ignored there. Everything I say will sink into the sea ... but nine days should be fine.
