Issue still not resolved, Breakpads replacements

Hi <br> <br> Please assist , I have sent my car inn for a service on the 25th September 2015. I was then notified that my break pads are worn off & was advised that I purchase others which I gave them a go ahead to replace. A day or 2 I have noticed that there was a squeaky noise when I push them ..I then phoned and was advised that I take my car back on the 3 October 2015 which I did. The Manager advised me that they may have installed cheaper break pads & they will replace them. I am not sure if that was done because I am still experiencing the same problem. I was clear to them that there was a funny noise when I drive my car on the left from the door. I am still experiencing the same problem until to date. A noise when I am driving by my left door & the noise from the brakes..I am very concern because I have raised these issues with the branch while I was still in my maintainance plan. Now that my maintainance have expired I don't think its far I fix these issues out of my own pocket when the job was not done.
