[Resolved]  Aquaguard Booster With E - Boiling — Even after servicing water is not coming from the aquaguard

Dear Sir/Mam
I m Hariom Gupta from Gwalior using aquaguard booster with e-boiling since last 2 years.We are on a 2 year service contract that we annually renew.
Since last month water is not coming in proper amount from the aquaguard.I have complained on last friday, i got no response, then i complained on saturday again no response.after complaining on monday, serviceman came on tuesday & he told i have to replace pump.On saturday he replaced the pump, even after replacing the pump water is coming at a very slow speed(more slower than before replacing the pump) & the serviceman told us i had done my work, now i can't do anything.
Kindly tell us what should i do now.
