Big Disappointment after buying manza

Car engine is not good but excellent, so as appearance but electronic ICU indicating sensors are totally flop case. Just on delivery and reaching home (30 km drive) three of its sensors gone. On day one it self car had to see the workshop for replacement of sensors. On third day another sensor (door open indicator) and next two days ABS sensor gone. Apart from above see the customer care of TATA, not bothered to attend the complaint not even out of courtesy. Nuisance system of call from Pune on visiting the service center inquire about silly questions like security guard wished you or not on arrival etc etc. But no reply of mails / SMS and even calls to regional office gurgoan remain unattended/ unsatisfactory replies on the aspect of performance.
