Did I get ripped off in a car inspection scam?

I took my vehicle to get inspected. They stated that my wipers were ripped and that they can replace them. I told them no and I would purchase my own blades to have them replace my wipers. They said no and failed the inspection on my vehicle. I feel that not only did they rip my wipers, but failed the inspection on my vehicle because I would not buy wipers from them. Can they do this? If they are not allowed to do this, where can I make a complaint?
