I ordered a phone case on Amazon just a little over a week ago (I wanted to track it because I can't get any information on Amazon about where it is), and the tracking number I was given for it was LN34010057200CN; but, every time I try to track it, it says it's a wrong tracking number or it can't be found. Whenever I try to track it on Amazon, all it says is, "No tracking details.Common reasons include: •Some shipping methods, such as Standard International, are not trackable. •Marketplace sellers sometimes do not provide Amazon with tracking information for their orders." Should I be concerned or just wait it out to see if my phone case ever gets here?
