We are in Chennai and have had a 5kg machine (SUP DX/M) and have been a staunch IFB supporter.
We have renewed AMC every year and were satisfied with the same. We have also taken care, by regular de-scaling, installing water softener, using the right washing powder.
However last year the contract moved to one CLASSIC Enterprises. The service is horrible. Worse still, the quality of the parts being replaced is so bad...
