Boulder Garage Door review: How do companyys like this stay in business

So the left spring on my garage door broke. Not a big deal I called the local repair place here in Broomfield and they put me off a number of days. So I called around and found Boulder Garage Door Company after a few others and they could come out today. Not that unusual so I said great. They showed up and after talking I gave the okay to do the work. I hung with the tech to see if I could help in any way. No thats fine. He did his job well and carefully and then presented the bill Okay I always pay my bills so all was good Cept one thing. After calling around and getting quotes after the fact I realized I was taken to the cleaners. A number of other local companys after given the list of parts and work done quoted me basically half what this company charged. Now I completely miffed at the fact that I was hosed Do not use this company. They a basically stealing from theyre customers. UGH!
