Complaint regarding a car purchase

My experience was terrible to date, no joy what so ever from sales man Lee. I purchased a T6 kombi and within the first 7days reported a fault with it ,I've taken it to tiger wheel and then to alpine for a second and third opinion. The right front wheel was reported buckled and then they say it's also the tire, they have taken the wheel into eagle wheels where it is still currently sitting waiting for the go ahead of a new tire from Nissan highway (Lee) and its now being 3weeks when no feed back unless I keep calling and asking. Don't buy from them or check the car properly and any faults with the car return it to the store until it's done.
