Tata Motors — Not finshing half day work

My car had an aircondition problem. Now its in tata motors authorised service center in thrissur - kerala. (Hyson motors - thrissur) i think the work will complete in half a day. But its day 16. There is lot of replies. No stock, parts on transist, vehicle is in check post, sale tax problem, courier service problem, will give you tommorrow, & tomorrow & tommorrow etc. . . No confirmation. Its very poor.

There is lot of notice, cards etc. . , "if the vehicle serviced any where outside, company will not give any type of warranty etc. . . But their service was very poor
