Roca India / Parryware — atlantis shower panel - horrible customer service

Address:

chennai, Chennai, Tamil Nadu, 600062

I purchased parryware atlantis shower panel on[protected] from krishna engineering. I installed the panel with texmo booster pump for good pressure as instructed by the seller.
But after installation i found the pressure from body shower is too low and i made a complaint with both parryware and texmo as i was unsure about which out of the two products is defective. My parryware complaint no is - cch/171019/43. The texmo guy came and verified everything and found no fault from his end. He also waited till the parrware service person arrived. Parryware service person investigated and told he is not able to find the root cause and said it might probably because of loop in the panel which he is unsure of. This shows his knowledge and expertise on this product and is really pathetic. My experience with parrware customer service is another awful thing. No proper response not timeline provided for the resolution.
The cost of texmo booster pump is rs.10000 and cost of atlantis shower panel is rs.19000. I get better customer service from texmo rather than parrware which ideally should be opposite. Parryware is a most trusted brand and i do not expect such a brand to have worst customer service and experience. Kindly take this issue seriously and provide a resolution at the earliest
