Ion Exacense Private Limited - Ion Exacense wrong service and money fraud

This is the worst company for servicing Aquaguard.
I had an issue * month back where the filtering was not going beyond * litre of water, After complaining the service guy (Name : Diwakar) told that the candles need to be replaced and took *, *** Rs.
Now did that fix the issue, no, there was a new issue the next day where the filter stopped working completely and started to give just * glass of "hot" water.
Oh and now, made ***'s of calls and begged this great company to send the service guy and fix the issue.
After almost * weeks, an another guy came (Name : Nagesh Gowda) and told the battery needs to be replaced and charged *, ***/- for the same.
Now did that fix the issue, no, now the *st issue came back again where the flitering was not going beyond * litre of water.
Now I have been calling ** times per day, and the response these people give is they will send a guy in an hour. I think in their case * hour is * week?.

I have call recordings and all the bills charged by these people and will be filing a case very soon.
