Got our 2 invoices the amount and the added extras agreed and signed, confirmed price on the phone also, went in next day to pay the amount, everything went ok we took the car home. 2 hours later the garage rang saying mistake on their end we owe them another £740! where do we stand? motability said we have to sort it with the garage Some advice would be great!
I think we would need to know a bit more before giving rough advice.
Is this £740 for optional extras you ordered on the vehicle, or is the £740 part of/all of the Motability Advance Payment?
What is actually written on your invoices (can you redact all personal and identifying details, scan in and post onto forum)?
Is the vehicle you received exactly what you ordered (same make/model/trim etc and same options you ordered)?
What error is the dealership claiming?
