Being in the same boat as many on here with extended deliveries and failed promises I fully agree with Bionic Rusty, at best, dealers are not being honest, clear or even fair with us.
I contacted Motability this morning and gave them the sad facts about the way my dealership had treated me and whoever I spoke to seemed genuinely surprised at the lack of help from my them. Motability spoke to the dealers and got back to me to say the dealers would definitely get back to me today with an apology and some answers. Needless to say, nothing at all from the dealership so I will be back on the phone to Motability in the morning.
