Centurion Locksmith exorbitant prices

I phoned this number, they sent someone out and charged me R2600 for 20 minutes of work. A security gate was jammed he just had to open and replace the lock. This is a loose group of locksmiths, there is no accountability or place to complain. I would strongly advise to not use this website. https://24-7centurionlocksmiths.co.za/
