Seventymm — Non-delivery of Sports Shoes ordered

I had online placed an order with SeventyMM for one pair of Lotto Sports Shoes, for a total sum of Rs 971-00, on 18th October 2012. They had promised to send it in 3-5 days. But I have not yet received the same from them. My continuous mails to them has not resulted in either the supply of refund of my money. I have send complaints on-line on[protected]twice), 25-10-12, 26-10-12,[protected]three times), 31-10-12, 1-11-12, 7-11-12 ( five times) and 8-11-12. Thjey are simply saying that it is delayed and nothing else.
I had received sms on my mobile informing that refund has been processed, and when telephoned they simply say that the transaction No. is [protected]. But I have not yet received the money back.
The activities of this organisation is amounting to cheating the public, and strict action should be taken against them, for this.
I should get my money back, and they should be punished.
Please take necessary action in the matter.
