Sometimes, in order to help you with a problem, we may want to take control of your PC so we can see what you are seeing or guide you through a problem. We sometimes do this using TeamViewer. It works for both Windows PCs and Macs, Linux, ChromeOS, Android, iOS and Windows Mobile.

To install it visit the TeamViewer downloads page, make sure it has pre-selected the right platform for your device and then scroll down to "Additional Downloads" and download and run "TeamViewer QuickSupport".

Once it's installed it will show you a nine digit ID and a password.

Now phone us up and tell us that information (don't email it to us!).
