Godrej Interio — poor performance of cabinet in modular kitchen

One thin cabinet moving on single channels (Top & bottom) needs replacement
The local godrej office is demanding 1600/-plus gst for servicing.
The same complaint has been attended twice, thrice during guarantee period of 1 year.
Being retired engineer it is advised to godrej interio to redesign above channels & replace them free of cost otherwise every time we have to go for servicing them. After all we have already spent twice/thrice comparing with other brands
The same thing has happened with one shutter of another cabinet which has been redesigned & replaced during guarantee period
Hope a quick action by company
