NO ONE CAN FIX MY VEHICLE!!!!!!

I HAVE A FAULT ON MY JEEP GRAND CHEROKEE THAT OCCURRED ON THE 29TH JANUARY. I PHONED PREGGIE ON THE 29TH AND BOOKED MY CAR IN TO BE FIXED. AFTER LEAVING NMI DSM ON MONDAY 1ST FEB - THE CAR STILL HAD THE FAULT. I TOOK IT BACK AGAIN ON WEDNESDAY 3RD FEBRUARY. THE CAR STILL HAD THE FAULT! I PHONED ON FRIDAY 5TH FEB AND WAS TOLD THEY WOULD BE ORDERING ME A NEW MODULE FOR MY VEHICLE. WHEN I NEVER HEARD BACK FROM ANYONE I PHONED AGAIN ON FRIDAY 12 FEBRUARY ONLY TO BE TOLD THEY DONT KNOW WHAT PART TO ORDER! I WAS NOT HAPPY AND TOLD THEM SO AND WAS TOLD BRADLEY WOULD CALL ME BACK! THAT NEVER HAPPENED! I HAVE JUST PHONED PREGGIE AND BRADLEY AND NEITHER OF THEM KNOW WHAT TO DO TO FIX MY CAR! I HAVE TRIED TO SPEAK TO DEES PILLAY WHO IS THE SERVICE MANAGER BUT HE IS NEVER AVAILABLE!<br> I HAVE HAD IT...
