Jabong.com — avoiding refund of paid amount

Address:	Gurgaon, Haryana
Website:	WWW.JABONG .COM

Recently i have placed and order with jabong.Com
it was a cash on delivery order... So paid and collected the order.
After i opened the packet the product was different than the one shown in the website... So mailed them the pic of the product and they arranged a pick up ... After the pick up was completed .. There was no response from them...So when i enquired they said that they cannot proceed the refund as there was no payment made when the product was delivered.
I got a call from the courier company and they asked the same i said i have made the payment
after that i have made many enquries with jabong and they said that as the payment was not made so they cannot return

if i have not paid how come they gave me a cash on delivery product and they did not make any enquiry with me about the payment ...Only when i raised a return request they realised that the payment was not made

when i asked them about this they said the delivery guy mistakenly forgot to collect the cash... If they have done that how come they didn't know for the following days and didn'tn complain at the address

so i would request you to plz see to the matter as i am facing the consequences of their fault aslo after i have made the payment
