Jaguar Bathroom Fittings — tap leakage

Address:

Varanasi, Uttar Pradesh, 221002

I have fitted jaguar tap in my bathroom. It have leakage, i have repair twice on my on expense by plumber. But issue still persist, my plumber said it's not the problem with fitting but there is a default in tap. I need jaguar engineer to visit my home and try to solve the issue. As there is lot of wastage of water.
It will be great if it's fixed soon.
