Day light robbery attempt by Suzuki East London

I write this complaint as I feel very disappointed as a customer of Suzuki. This is my 2nd time Suzuki East London is trying to cheat me. A year ago my brake started making a noise. I took the car to Suzuki 5 times in the last one year. Each time they will say they will skim the brake pads but the noise won't stop . The last time I went they said they have to change the drum to stop the noise and gave me a quote for R5 350.00. Not convinced as my car is only 60 000 kms I decided to take it to another mechanic that my friend recommended to me. He checked the car and found a stone near the brake pad. He removed the stone and cleaned the dust, all for R500.00 and the noise has stopped!!!!! I bought this car, a Suzuki Swift Desire in May 2014. At that time I ordered for the optional mag wheels paying an extra R5 000.00. They said they don't have stock and when the mag wheels arrive they will phone me. After 2 weeks when I went to take delivery of my new car I was shocked to see that they have put aftermarket mags and 14 inch tyres instead of the 15 inch tyres which is the correct size for my car. Who in this world would NOT know that it should be a Suzuki fitting that should come on a Suzuki car? I had to write several complaints to get this sorted. Now what would have happened if an innocent client give in his car to change the drum as they had told? Would they have changed the drum? And to remove a stone do you have to pay R5 350.00? I have their quote with me still. And the joke is they were all insisting and giving me explanations as to why I should change the drum. The lady at the reception even wanted me to place an order. She says it has to be ordered.q
