That's weird. Is it just a Switch 2 thing you can't cancel? I've cancelled pre orders from Argos in the past by calling them up.I managed to get a pre-order in with Argos very early, but worried I am essentially paying a lot of money just for Mario Kart at this point.
A warning to others, it is currently impossible to Cancel my Argos order, so I am stuck with it at the moment. Not sure I have the will power to turn away the delivery when it arrives which seems my only option now.....
