smart ways to dupe customers

While buying just to sell everything was well, Starting with Service experience true picture of company got reality check 1) Car was suddenly accelerating without acceleration I got saved from accident twice, asked team for check they took appointment but never came for inspection 2) average of any car should be atleast 8+ this car gave 6.5 avg, asked for same they never came back for it 3) gave for body shop & insurance, imagine the service company din do the job correctly infact they bumped the car and gave it back thinking they can smartly bluff and not get caught shame PATHETIC is the after sales please don't buy if you want to burn the money
