WORST CAR WORST TECHNOLOGY

i HAD PURCHASED TATA HARRIER BLACK EDITION XZ MODEL ON 5TH JAN. LATER ON I HAD OBSERVED THAT THE BLUE TOOTH IS NOT WORKING PROPERLY AS I WAS UNABLE TO TALK WHILE DRIVING. THE SOFTWARE WAS UPDATED BY THE SERVICE CENTRE AND THE PROBLEM IS INCREASED AS THE DISPLAY SCREEN SHUTS OFF ANYTIME ANYWHERE ALONGWITH THE SPEEDOMETRE. THE TATA TECHNICIANS ARE UNABLE TO UNDERSTAND THE PROBLEM AFTER 5-6 VISITS IN THERE SERVICE CENTRE. I M FACING THE PROBLEM FROM LAST ONE MONTH AND NO ONE IS TAKING CARE OF THE PROBLEM. MY NAME IS CHETAN FROM JAIPUR 7413000001
