Independent Car Radio & Aircon in Zwartkop, Centurion are DISHONEST

Unfortunate to say these people are very dishonest. My aircon 'working. I took my car to them, they put gas and told me to go back a week later to check for a leak. I didn't go back. After a month I was without a aircon again and I went back. They said the first time I took the car to them they only filled gas and didn't check for any leaks. They checked air con and told me there was a leak in the discharge pipe which would need to be fixed. The quote was about R2500. I then went to another company, I told them I had a leak and how much would it be to fix. They told me there was no leak. They put gas and 4 months later I still have air con. I am furious with Independent Car Radio & Aircon in Zwartkop, Centurion. The first time I took my car to them they obviously put a small amount of gas in, knowing that it would only last a month and I would be back. Disgusting how companies like this take people for a ride. If I had the money I would have paid R2500 for dishonesty
