Spokane Hyundai

I bought a Hyundai Elantra 2018 new on September 2018, while they were trying to convince me to buy the car they offer me with a purchase a 1 year of full service oil change filter etc, how disappointing was when l schedule the first service a week a go and they tell my husband there was not a such thing and we have to pay(of course we did) but for sure this will be the last time we serve with them and we buy from them, l call them and look all the papers and it’s not written so l can’t said anything else other than DONT TRUST THEM make sure everything is writing because they promise everything to hooks you up
