I don't think VB(UK) will be impressed with their approved dealer/fitter sending out a completed install without a full testing and commissioning; unless it's the 1 in a 1000 that goes wrong virtually straight away.
VB are a top notch company, I'm sure they'll sort it for you, even if your dealer can't.
