AFTER WAITING A MONTH MY CAR CAME BACK MORE DAMAGE

I TOOK MY CAR IN TO VW IN DECEMBER FOR THEIR OWN POOR QAULITY OF CARS DAMAGING BEFORE 60000KS, I WAITED A MONTH FOR MY CAR TO BE REPAIRED IN THAT TIME I HAD TO BEG FOR A COURTESY CAR WHCIH I FINALLY RECEIVED, A MONTH LATER MY CAR WAS REPAIRED, WHEN I PICKED MY CAR UP I DROVE IT FOR A WHILE ONLY TO REALISE THAT MY STEERING IS SO MUCH HEAVIER AND IT DOES NOT FEEL LIKE I HAVE A POWER STEERING, I CALLED MICHAEL FROM VW AND ALL HE SAID WAS THAT HE DID NOT WORK ON THE STEERING IM SORRY, I GOT FULL MOTOR PLAN AND EXTENDED WARRANTY ON MY VEHICLE,IF MY STERRING WAS FAULTY BEFORE IT CAME IN DONT YOU THINK I WOULD HAVE TOLD VW SO THAT IT CAN BE REPAIRED ONE TIME, WHAT TYPE OF SERVICE IS THIS, I PAID R4000 FOR THE CAR HIRE,NOW IM ASKED TO SMS SOME UNKNOWN PERSON MY BANKING DETAILS FOR MY MONEY TO BE PAID BACK, ISNT THERE A FORM I SHOULD HAVE COMPLETED WITH MY BANKING DETAILS IN ORDER FOR MY REFUND TO BE PAID, NOW I GET A SMS FROM AN UNKNOWN PERSON TO DISCLOSE MY DETAILS, IS THAT HOW VW WORKS? WORST EXPERIENCE EVER IN MY LIFE
