Toyota

In oct 2018 took my rav4 to Toyota town on hammer Ln Stockton ca. Front & rear brake job. Returned twice because of rattle. They did not replace anti rattle clip and I was told they did not carry. Kept my car for couple days to fix. Now my complaint. Had my oil changed today (not at Toyota!) was told brakes needed pads replaced. I took my car to mechanic to check & he said pads were good but did I know that Toyota used aftermarket pads? He checked numbers on pads and they are not same as numbers on my work order. Is this legal to do? I took my car to Toyota because I wanted it to be done correctly. I am very disappointed. I complained in 2018 & now again for the same thing...questionable work.
