Skoda India — Unsatisfied with service by BLC autosales pvt ltd Hisar

Address: Hisar

I went to BLC autosales pvt ltd Hisar for my Skoda rapid bearing Reg no. HR20AD1341 routine service.
Nobody attended me on the workshop. Even the job card was not prepared. Then a person without uniform came and drained engine oil from my car and poured engine oil of petrol version in my diesel engine car.
Then I saw the grey plastic bottles and objected about this. He drained the petrol version engine oil and poured diesel version engine oil.
My Car's display digital meter is malfunctioning after the service. After so much negligence, the staff forced me to give 10 points if asked for feedback of service.
Kindly take proper action for this negligence...
