WORST DEALERSHIP SERVICE EVER

I WENT TO NORTH RAND ROAD DEALERSHIP TO PURCHASE A FOTON DOUBLE CAB. WHEN I HAD TO GO BACK TO SIGN THE SALES PERSON I ORIGINALLY DEALT WITH WAS NOT THERE. TWICE THE WRONG FILES WERE BROUGHT FOR ME TO SIGN!! WHEN I ASKED WHAT THE APPROX. COST FOR A SERVICE WILL BE WHEN THE MAINTENANCE PLAN EXPIRED, NO ONE IN THE WHOLE DEALERSHIP KNEW!! I IMMEDIATELY CANCELLED THE PTO AND WENT TO THE NEXT CLOSEST FOTON DEALERSHIP, EDENVALE. AFTER PROMISES OF DELIVERY OF THE VEHICLE A CERTAIN DATE NEVER TRANSPIRED, MY CALLS THEREAFTER WERE NOT RETURNED - THEY BASICALLY JUST FORGOT THAT I EXISTED?? EVENTUALLY TOTALLY FED UP I WENT TO THE DEALERSHIP AND DEMANDED EXPLANATIONS FROM THE DEALER PRINCIPLE, MICHELLE, WHO WAS MORE THAN WILLING TO RESOLVE THE PROBLEMS! MY BIGGIST CONCERN NOW IS, IN LIEU OF THE BAD EXPERIENCE AT 2 DIFFERENT BRANCHES AND REPORTS FROM INDIVIDUALS ON 'HELLOPETER', WHAT KIND OF SERVICE/NON SERVICE AWAITS ME (I ALREADY PAID A DEPOSIT) REGARDING FUTURE SERVICES OF THE VEHICLE???
