Kent RO — Replacement of filters which are in warranty

Address:

VPO BADSHAHPUR,MAIN SOHNA ROAD, NEAR SBI BANK , GURUGRAM

I have changed my filters and membrane around a month ago and now they are not working and ro water is blocked.I paid 3500 for them and they are in three months warranty. I am complaining at kent service centre since three days to replace them but no one is changing our filters. Such a bad experience from kent!! Cheap filters which can't even last for a month.Total wastage of money!! If they can't change filters then what is the use of them being in warranty i can't understand. Never expected this kind of service. Are we fool who will pay around 4000 every three month ?
