We recommend tracking directly via your local postal services tracking page (such as USPS if you're in the US), as sometimes there can be a delay with the parcels current status updating on third party websites.
You can also track via Royal Mail here to see the last known status, or to see if the parcel has been processed by them.
If it has been 45 business days since the last status update, drop us a message customerservice@shopdixi.com and we can help.
