I am using aquaguard since 10 years, nice product but worst service. They come at your doorstep for sales many executives come but once its delivered, no one ll turn up.I keep calling customer care they put your call on hold for min and min, they say it ll be solved within a day . no one all comes .escalation department says they all give a call back never you ll get . I have spoke to supervisers(saravanan, praveen)and many more who give false promises . I suggest not to purchase only because of worst service .
