USA Locksmith pricing scam and long waits Manassas, Virginia

I locked myself out of my house and called a number from the local area that I found online that was close to my house.  The phone was answered as "USA Locksmith".  I said that I had locked my keys in my house and needed my front door opened.  I asked for an idea of how much it would cost and was told that it would be $25 to come out and $45-65 dollars to open the door.  I asked about how long it would take for someone to get there and they said a half hour.  I gave them my information and was told someone would call me right back.  A half hour later, no call.  I called back; they had taken down the wrong number.  They put me on the line with a technician who said he was leaving to meet me at my house right then.  I drove the 5 minutes to my house and waited for another half hour.  I called back.  They said the technician was still 20 minutes away.  40 minutes later, a brand new technician called and said he had just gotten the page about the job.  He would be there in about a half hour.  When he finally arrived - it was now over 2.5 hours after my original contact and I had been locked out for over 3.5 hours counting the hour I spent trying to find a locksmith.  The technician said the charge would be $30 for the call and $185 dollars to open the door because it was "an exterior door" which was obvious when I first asked for the estimate.  I paid because I needed to get into my house (it was now after 5 pm) and I had my two kids with me.  I tried called the customer service number repeatedly and could never get through to anyone.  I finally reached the "manager of the entire region" 4 days after the incident and he was as rude as could be, informing me that I should have understood that what the phone person told me was "just an estimate".  When I tried to reason with him, he kept cutting me off.  He also told me that - despite being the manager of the entire region - he had no idea why no one answers their customer service lines.  Steer clear of this company - they are low-life from the very bottom to the very top - obviously.  I am shocked that businesses like this continue to operate.  I wish I had done more research.
