Consumer Redressal

I bought 6 LED bulbs from Shopclues.com on 23rd Feb, 2015, (Order ID: 39213525). The order was shipped through bluedart (consignment no. 69234145061) on 25th February, 2015 but It is stuck somewhere (CCU BDA warehouse) since 27th February, 2015.) The bluedart branch at imphal also has no information on the consignment since it didn't reach Imphal. But the shopclues customer support is insisting that i have received the product and refusing to refund my money. They are not able to give any proof of the delivery also. What do I do now? Such fraud company should be banned. Regards Mayengbam Jaganivas Singh
