Jaquar — Water Leakage from shower while using main tap

Address: Navsari

Hello team - i logged a request last week as there was a leakage from shower while using main water tap. Service engineer came to my place and did the service (This was not required and was not even asked), replaced some part charged 1400 ; has not provided me receipt and the problem is not solved. I sent the video to the agency and instead of offering me a help and correcting their error they are putting a blame on us - this is unacceptable at any standard. I am attaching a video of the leaks that i sent to the manager - to the same manager i informed that engineer charged 1400 and not given me receipt - he promised to deliver a soft copy of the receipt but that never came to me despite 4 days have gone
