BAD SERVICE

I BOUGHT A CAR AT THE BRANCH TOOK IT HOME ,WHEN I GOT HOME I REALIZED THAT THE CAR WAS NOT LOCKING (WITH BOTH MANUAL AND MOBILIZER KEYS) TOOK THE CAR BACK TO THE GARAGE AND I AM TOLD THAT THERE IS SOMETHING WRONG WITH THE MOBILIZER,EXPLAINED TO THE MANAGER THAT EVEN MANUALLY THE CAR DOESN'T LOCK,SHE JUST SAID WELL THAT IS NOT THE GARAGE'S PROBLEM,THIS IS A REALLY BAD SERVICE,AFTER PAYING SO MUCH FOR THE CAR I DIDN'T EXPECT TO BE TREATED THIS WAY,
