Hi, the plug, coming from the white wall mounted unit (fttp i think) has exploded. Spark, bang, & split in 2. Has this happened to anyone else? Called virgin, usual 3 attempts & over 2 hours of waiting & now have to go days without tv or WiFi until they can fit us in. Just wondering if anyone else has encountered this. It was plugged into a surge protected adaptor & all other plugs are fine.
