Hyundai Motor India — postscript remember

Address:

Jodhpur, Rajasthan, 342602

I have serviced my hyundai i10 car from raja hyundai service centre jodhpur thay charged avergae 5500 rs from me including labour charge i told them about my problem but they dont resolved any of one and charged individualy for service. They only changed oil other remain same. I called many time but they postpond all my query and disconnect my phon saying we will see but now it cant resolve. And i also want to know that during service they charged every parts charge to change.
Please resolve it other wise i change auto service.
And there is not any processor to give old part to custumer istead of new
