Coolant leak

My wife called and told them the problem we were having with my Nissan pick up. They said bring it in we will check it out and let you know how much it will cost to fix. They checked it out and said it would cost 200 to 300 to fix the problem. We said go ahead and do it. They called back and said well it might be 375 or more to fix. We said no we can't afford that. They said it will be $39.95 to put it back together. They never said there would be a charge to look at it. They have worked on my van in the past that's why we called. We will not do any business with them again. Very shady.
