[Resolved]  Olx India — Internet Scam, and the seller is mentally torturing me asking me to further amount

So this is what Happened. I happened upon a page in OLX india (Bangalore) about a seller with a Cannondale Scalpel 29er (2013) price for a quite a cheap amount. (Sigh) I should have been more cautious about this. However I got in touch with the seller and the way communication was everything was professionally done. So enquired about the payment and this scumbag quotes a price and says he’ll get it delivered to me in Kerala, though he is in Bangalore. So once I had made the payment, he acknowledge that he received it and proceeded to send me the courier serial number through which he was sending the consignment. Now the screw up is, the sender’s secretary sends me a mail today morning with the invoice and to my surprise along with the bike I ordered, there were 3 additional bikes with a whopping amount that could break my wallet. I contact the sender and point this out to them, and he says since the consignment has already been sent there is no way they can recall it. And asks me to pay an additional amount to cover the entire cost of the other bikes as security and that they would refund me when I re-ship the bikes the other 3 bikes back to them. I tell them that it was their mistake and I just want a refund for the amount that I paid for. And I tell the dick butt that I’m going to file a complaint at the consumer court he says, its unnecessary and the refund processes will only take longer I’m at a dilemma please help me out. They are asking me to pay more despite the fact that I had paid the entire amount for the bike. I can send you the entire e-mail transcripts on request. Kindly take this as a grave manner and do the needful. An unwary shopper scammed by internet thieves through OLX. Yours Sincerely, Vinay
