Complaint Review: Locksmith Pros

On 12/2/16 my friend got locked out of my house.  I was at work and could not get home.  It was cold outside & she was wearing no shoes & no coat.  I did a search online for a mobile locksmith in Van Nuys and found this loser company.

The guy said he could be there in 15 minutes and I said fine but call me with pricing.  I never heard from him til about an hour later when my friend told me the guy told her I needed a new lock and she let him do it but he NEVER told her how much it was going to cost.  When all was said and done he charged $711.00 for a lock that looks like it cost $5.00 and I could of bought at Home Depot.  I contacted this company several times and they are very rude and hang up on you all the time.  I asked for their mailing address and they said oh we are located in Dallas, TX and I said then why do you have an 818 area code number and again they hung up on me.  When I first called to compalin about hte price I was basically told too bad that's how much it cost.  I did file a complaint with the BBB but they had no success contacting htis place.  I hope someone can help, I would like to get at least half or more of my money back and stop them from ripping off the next person.
