After Sales Horrors

So my fiancée took delivery of her vehicle on the 12/12/2019. Upon inspection of the vehicle we found that the spare Tyre that we received with the car was old and had no tread left definitely not roadworthy and if used she would get fined if stopped my a traffic officer. Not to mention if she gets into an accident the insurance would not pay out. This was reported the same day to the dealership. With the driver that delivered the car as a witness... The date now is 07/02/2020 and we are no closer to any reasonable resolution to this issue. As there are internal processes to be followed to find the culprit.... So instead of assisting the customer then investigating rather anger them. Sounds smart. Not to mention having to resign the contract 3 times as there were mistakes made with the pricing that my fiancée picked up. Passing of the buck and no accountability seems to be the theme of the day{more like 2 months less a few public holidays naturally}. The following staff were "assisting" Savannah - sales lady that had her "hands tied". Alfie - The invisible man. (no reply to emails and could not get him on the phone).
