We Buy Cars quality and Decra grading : Questionable

After I purchased car with some hiccups I drive the car for 2 days and heard strange noise at the right rear wheel.i drive to the workshop I usually use and saw that the brake caliper was totally lose and tat both bolts that is suppose to fasten it was missing. This together with a lect front strut that was not securely fastened and a right rear shock absorber that is totally shot let me answer at the buying an selling process of the company and the relation and or care for customer safety. It also place a question mark on the Decra grading as this vehicle was given a Platinum grading by Decra. It make one to wonder if business targets and turnover have replace customer care and safety.
