Sunflame Enterprises — service charge issue

Address:

122101

The customer care said they would charge 350 for the service. I was fine but when the guy came he said that 350 RS is only visiting charge. And Service charge would be 100 extra. Why would I call a person just to visit and see the gas burner. This is utter nonsense. They should have cleared it before booking. Suddenly in between the service(btw no parts were removed only checked by the technician) he asks 100 RS more. Be clear in terms of money before booking I don't mind paying extra 100 but it should be ethically done before.
