Consumer Redressal

Hello Sir/Madam My name is Vinay Hegde.I\'m a resident of Bangalore, I purchased a external hard disk Toshiba Canivo Basic 3.0/2.0 1TB on 10/03/2012 from Raju Electrocentre SP Road Bangalore.(For the purchase I Have a tax bill) It started to giving me problem so I went to Rashi Peripherals PVT.LTD(Toshiba External Hard Disk Service Centre) and they replaced my hard disk(For this I have a receipt), now its also giving me problem. I went again to Rashi Peripherals, they are telling its out off warranty. But the warranty of my hard disk was 3 years. But the warranty means It is applicable from the date of purchase.According to that my warranty will be upto 09/03/2015.They are not understanding this. They are making me roam around between Rashi Peripherals and Raju Electro Centre. They are wasting my valuable time and money. Please help me and give me justice for this
