Jaquar — bath shower

Address:

Chennai, Tamil Nadu, 600099

We bought bath shower in june 2018 and started using from july/aug after
House completion... We have put a grundfos motor for maintaining pressure as well. We installed a instant geyser 2 weeks back but since then the shower is not
Working properly.. Sometimes pressure is there but other times its very slow or not coming at all. We approached the shop we bought this from - lakshmi sanitation, chennai - but they advised to approach jaguar directly on toll free number. But this toll free number is not going through.
