Ebay.com — Refund not received

Address:	New Delhi, Delhi, 380007

I bought an I phone 5 from eBay in July by cash on delivery service, the day I got my phone I paid them at that moment, it was damaged so I further contacted eBay then they asked me to send it back . I sent the phone by courier and they received it on August 25, 2015 . after that they told me that they will pay my money back via demand draft DD . and now it's been more than a month and they have still not sent my DD . I am worried now . eBay doesn't reply to my mails properly and mostly they don't reply at all . and when I call the helpline they don't tell any details that when I will get my draft, they only tell me that yes it is in process and we will get back to you soon . please help me what can I do . EBay claim Id is 1168877. Thank you .
