WORST SERVICE EXPERIENCE EVER

DO NOT TAKE YOUR CAR HERE, STAY AWAY THE SERVICE IS PATHETIC. MY CAR IS LEAKING OIL AFTER I HAVE TAKEN IT FOR A SERVICE AND WITH POOR CUSTOMER SERVICE. THERE IS SMOKE COMING OUT OF MY CAR AND APPARENTLY THEY HAVE A 6 MONTH GUARANTEE BUT THE CAR JUST COMES BACK WORSE EVERY TIME I GIVE IT TO THEM. SO I HAVE TAKEN IT IN FOR A SERVICE AND MY CAR IS STILL BROKEN. CAR CANNOT START LIKE HOW IT USED TO, THE CAR DOES NOT ACCELERATE LIKE HOW IT USED TO.
