[Resolved]  Kent RO — unnecessary service charges

Address:

Bangalore, Karnataka, 560087

I am using kent ace water filter for last 2 years, had some water quality issues in jan 2019. Service technician came and replaced the filters which costed around 5050 rupees including visiting charges. Technician told that there is an 3 months warranty for replaced spare parts.
After 2 weeks, filter stopped providing the water, placed an sr again for which the technician came and replaced some 50 rupees spare and charged 300 as visiting charges.
Its not even 3 months, i am hearing some beep sounds from the filter. As per the manual, it is an indication of filters replacement. I called up the customer care to register a complaint on the issue, but they are unwilling to send the technician without payment of visiting charges.
My concern is that because of kent spares quality issues, customers are made to pay for service charges which is really unfair and is the wrong policy of kent.
