Orders are sent out within a few days most of the time, but delays can happen for any reason.
Sign in to your Boohoo account and go to "My Orders" to see the progress of your order. You can find the most recent information about the status of your order here.
If your order is still "processing" after more than a week, you should get in touch with Boohoo's customer service for help. You can get in touch with them through their virtual assistant, or through their "Contact Us" page at https://www.boohoo.com/page/customer-service-contact-us.html
To speed up the process, please have your order number ready when you call them. They can give you more information and help you fix any problems with your order.
If you have experienced a similar issue, please feel free to share. You can also file a complaint on Xolvie.
