Consumer Redressal

Hi Ihave placed an multiple order through rediff shopping on 15th sep2013 Iplaced six order at same time but they gave me only one order number and said it will be delivered at different times. After 15 Days i asked them I got only three where is my rest of the things. They said be patient they will be delivered to you shortly .After waiting for a week I again asked them where is my order and they are saying its already delivered, though I haven\'t received anything. The number they are providing is not in use they are not answering my mails and just ignoring. I also try to contact the courier company giving them the tracking number provided by rediif , the courier company said we haven\'t received any kind of parcel like this. My order number is 8533270 also providing the tracking number of the things which need to track through aramex.com are as follows 40121723246, 40121723224 , 40121723235. Please help me with this situation and let the others know that they are rubbish.
