It's Grand Prix Mazda (not Crownpree as per a previous commentor). They're not a telemarketer - should only be calling you if you've put your car in for a service there (or perhaps enquired about servicing, or maybe even buying a car).

I called back number (07) 3863 8133 spoke to a woman who said company name is Mazda.
