Mine (Bristol Street Durham) Motability person (Lisa) was very good, emailed me straight back when I asked about Sync4 not being fitted and confirmed that was the case, she did say they were told it would be at the time of order.
As soon as I said I’d cancel and either wait for the facelift or look around for something else she emailed me back saying she’d cancelled it and removed it from my Motability account as well.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
