@Cornish Pixie: Please head to Settings > About tablet > Serial number, and double check that the number you're entering is correct, and that there are no spaces before or after the number when you enter it. If your tablet was intended for use outside your current region, then this can also create issues, as our database will only recognise serial numbers for devices that are registered in, for instance, the EU.
If you're still having trouble booking your tablet in for repair via our online portal, then please reach out to our Support Team by following the link below, and an advisor will be able to make the necessary arrangements for you.
