I'm having problems with the ambit 100 too, I have a thread here.

I have been phoning VM customer service, trying to explain the problem but it's like banging your head against a wall. They kept saying things like clear your cookies on internet explorer. I told them I don't even use that browser but they wouldn't listen.
These problems have been going on weeks now and I've have enough, I think it's time for me to call disconnections.
I hope you get your problem sorted daz215
