Ford India — very very poor service

Address:

Vellore, Tamil Nadu, 632006

Hi team,

I am from vellore which is in tamil nadu.
I hold a ford figo vehicle which i gave for service last week in sarvesh ford service and was charged around 8000 for service.
There was some problem in vehicle and i have reported before service but it is not fixed. When i went again they are telling me to pay 33000 because injecter is not working.
How come they have not found it during service and now it is not working.
