Mavis Discount Tire

I bought my car in for repairs at the Lake Charles location. After the repairs were done my car was making a noise. I bought it back for them to check it again they claim I needed 2600 more of work done on my car. After I dropped it off after several attempts cause they was always shorts handed they then told me I didn’t need the extra repairs. It was a clip that they didn’t put on the piece they had already changed. On yesterday my car started to make another noise so I bought it to the location in Lafayette with my paperwork and nothing on the paperwork was changed on my car. How can we resolve this
