I have been using ifb dishwasher for the past 3 months. let me tell u that the service centre at vizag is very poor in responding to requirements of detergent salt and rinse aid. It takes atleast 10 telephone calls and arguements on daily basis before any requirement is supplied by them. This is not expected of a reputed company service centre. A responsible person is requested to look into this and improve the service otherwise whenever a reference is made to me by other possible customers i will not be able to give a positive view.
