Wrong Springs Installed without notifying anyone.

I had my garage springs replaced, 2 torsion springs, 4 wheel and a cable for R10150-00. Installers left and 3 days later the garage gave me the same error. I phoned another company for a second opinion and cost R1100-00 which they then told me the wrong springs are installed. I then phoned Garage Door and More and let them know about the issue, they came out and replaced the springs with the correct ones. Point is, would they ever have told me that it was the wrong springs if I did not get a second opinion? I don't think so. I requested the R1100-00 from Garage Door and more and they told me that they have not told me to get a second opinion. Last Point if you want to fix your garage twice for the same problem and twice the price, they are the guys for you
