Hyundai Motor India — Cost of service of verna

Address:

Jaipur, Rajasthan, 302015

Service of my verna at 60000 kam was estimated ₹7800/-, when i submit my car to the service centre. after 1 hour the service advisor call me and said that break pad of ₹1600/- and coolant ₹800/- will be changed, and i said ok for that. again after an hour he called me and said that wipers also has to be changed and a pipe of turbo has to be changed of ₹4800/-.
Again after an hour he called me and said that motor of wiper is not working, and it also has to be changed. this time i got a shock as i am using wiper on daily basis, and it was perfectly in working condition.
Then i called to customer care regarding this, a lady pick up yha call and asked me to hold the phone, but she did not turned up even after 15 minutes. ao i cut the phone.
This is completely unprofessional from company's side.
I want immediate action on this.
