Nissan Motors — poor car service

Address:

Pune, Maharashtra

I had a very bad experience about nissan customer service about car second free service faced at landmark nissan workshop, bawdhan, pune.. I took appointment for car service on sunday 1/07/2018 morning.. But when reached at workshop at 10-30 am actually they took my car at 1:30am even though there was only 4 number in front of my number..
I observed below few points about workshop..
1) shortage of technicians
2) technicians works with mobile head phones put in ear..
3) no supervisory control
4) no any customer relationship manager assigned to me
4) car service period longer than actual
5) poor technical abilities of staff..

I think please take this points on priority.. And revert to my queries on
