Boohoo's rules say that they can't change the delivery address after an order has been made. That being said, if they or the carrier made a mistake, they should help fix the problem.
Get in touch with Boohoo's customer service right away to fix this. You can get in touch with them through their "Contact Us" page, which gives you ways to email or message them on Facebook.
Give them your order number, information about the wrong delivery, and anything else that will help them look into the problem.
Also, use the tracking number that was sent with your shipping email to keep an eye on your package. This can help Boohoo find the package by giving them information about where it was brought. If the package is sent back to Boohoo because the address was wrong, they will issue a refund as soon as they get it.
While you wait for an answer, keep an eye on your email for updates from Boohoo's customer service. If you don't get a satisfactory answer within a fair amount of time, you might explore Xolvie to read about the challenges others have faced and share your story.
