Toyota — Fraud by service center

Address:

Bilaspur Chhattisgarh

I have done service in service center after that my ac not working properly and they have disconnected my lights unessery and they don't let me to see my car what is happening to it ..
This is the major drawback in india customer should be allowed to go inside the service center room because in india frauding is a common thing they put parts of different vehicle and sell the brand new parts
