If that is the case in each car serviced, this charges for consumables should be standard charge across all ASCs. But they are not. Secondly, are these Tata-approved charges? I don't think so. Thirdly, eventhough these are not standard Tata-approved charges, assuming that these charges are used for better service than others then will KHT give this explanation to savinvas in writing? Rs. 250 is not important and he has already paid. But let KHT makes it stance clear. Forget giving it in writing, after several attempts - first with SA and then with owner adit hmself, they have not given clear cut details to savinvas. Let KHT state above details towards Rs. 250/- consumables. In all probabilities, it won't do it and we know why. These all are covered in the basic 3-4 questions we asked for which we are awaiting response from KHT.
