Eureka forbes,

We had purchased an ag reviva vide invoice no.[protected] dt.8th July,06.
its not working properly and we have changed the candle thrice by paying the amount 250 each time.
while complaining we are advised that it will work like this and can not be improved ,since our sector-30 in faridabad is having lot of dust in the water. since we have purchased the instrument on the condition that it will purify the water properly ,hence you are requested to take back your product and refund the amount paid by us. Immediately or replace it with proper instrument. Failing which we have no other alternate but to move to the consumer court. kindly reply us, within a week.
