If your V6 is stuck in the reboot loop and won't startup, it has a fault and you (almost certainly) need a tech visit.
The quickest way to report service-affecting faults is to call, and it sounds horribly like you've been given the brush-off rather than the person you spoke to, actually dealing with the problem by booking that visit.
I would suggest in the first instance, calling back - hopefully by speaking to a different agent, you get the correct outcome. If not, then post back and the forum staff team should pick this post up in a day or so.
