Consumer Redressal

This is to keep you informed that i have given my Croma 3G Tab GAN number BAN201113WS00009, Product id 175298, Serial number 911323900004098, Purchased on 22.09.2013 for service to your Croma outlet at Koramangala, Bangalore since the SD card was not getting detected. It is very upsetting that there is no feedback from Croma since last 12 days on the status of the product and when it will be serviced and returned. I am virtually following up with the service team but the only feedback i get is that the product is still in service. I have paid good Rs 14,000 for a product that has failed within 45 days from the date of purchase. Please help me solve this issue
