Aquaguard water purifier NF(RO)Membrane
Not providing proper service

I have been using Aqua purifier since 10 yrs. Last Year I have changed another one NF membrane (same company). After every 6-8 months change its Nf & other membrane including candle. Last time also came with loose Nf membrane, after complain many times they came with packed membrane.

Complaint to Laxmi Nagar service centre & also to Euro Help Line 39883333., but in vain.
