Such a bad organisation; no clear policy with lot of Hidden cost. Single Rubber spare part charge is more than the full AMC charge! They bring parts without any sealed cover! I was surprised to see a refurbished Drum, the person was carrying it on his shoulder when he came for replacement!The engineer will cook nice stories of parts not working well and bundle it as free of cost with AMC. And then they come to replace it with 3x/4x charges of Rubber and plastics! I think there are much better alternate products with transparent policies during AMC.
