Did they loose your car? or were they mean to say, we have found you a car, it’s at the port and needs to be transported to the dealership, which may take 3 or 4 weeks, with a handover date to yo in April? Did the salesman mistakenly think the car was with the dealership, only to correct his mistake after you had asked for a handover date this week or realising the car they thought they had was indeed for another customer, thus bursting your bubble knowing you won’t have it now till April. Or is there something Fishy going on!
Perhaps pay a visit to the dealership in person and ask whats going on face to face.
