Consumer Redressal

I bought Eureka Forbes water purifier, named AquaSure Amrit on 13.4.2014. I have two major complaints. 1.In less than 5 months the tap assembly broke, the techinician said it is not covered under warranty and charged me Rs.150 for replacement while the warranty says it is covered for first 6 months. 2.The purification cartridge is supposed to purify upto 750ltrs of water however it is not even purifying 400 ltrs and already all three cartridges got used. We are only 4 members, hardly use about 10 ltrs a day. I had to buy new cartridge for Rs.280. 3. The technician charges Rs.100 for visit which is not disclosed in warranty. I think Eureka Forbes is running fraudulent and manipulative and false promises based business. 3. There is no easy and customer friendly complaint redressal system in place, their complaint phone is always busy. The system discourages customers in lodging complaint. I want to return this product, get full refund and + Rs.250000/- compensation.
