My Wifi pod overheated and stopped working

I am a long term customer and have a white pod that was working perfectly.  Two days ago it stopped working and when checked it was running extremely hot. Much hotter than I want to leave plugged in. This suggests to me that it is broken at some level.

I would like to order a replacement pod so we can get back to enjoying wifi upstairs.

The Virgin Website and Automated Phone system sent me round in circles running completely unnecessary tests and provided no method to inform Virgin of the issue or ask for a replacement.
