Terrible customer service- unfair treatment of client

On the 18th Oct, I booked my car in to be checked at Peugeot Northcliff for a noise on my brakes and other things. On my arrival to pick up the car in the afternoon, I was told that the brakes have been checked, dusted as well as that sometimes causes the noise but I was assured that the brake pads were still in good condition by a lady called Elise. She then recommended that maybe I should take the car in for alignment. I am no expect with cars but I couldn't understand where this alignment fits with the noise on the brakes. I had to use the car for a week with the same stress and eventually returned to Peugeot the 2nd time on the 26th late afternoon. I was told to return the following morning as it was late, I couldn't the following day due to work constraints. With all of the frustration I took my car to HI-Q on the 28th to be checked, they found that my brake pads were worn out and that I am driving on metal to metal and replaced them. I paid R1450.01. I contacted Peugeot to inform and enquire on this matter as my car is still on the maintenance plan and what is my recourse only to find myself dealing with an arrogant service manager. Below is his reply to my e-mail this morning :

Good Morning

I understand that your frustrated but the vehicle had to be brought back to the dealer to check it and replace it at no cost to you. When the vehicle was checked by us the brake was still with in spec. If there was a problem with the brake it would have been changed.

I went to dealer twice, and this is the response I get from the service manager? Utterly disappointed!!
