Automatic Renewal Refund

My credit card has been charged with automatic renewal of Bitdefender internet security 2013. I am not even using the product. Even though i created a ticket for the refund, i have got no reply. I understand that you have a 30-day limit for these things. I request you to refund me my money before the limit expires.

I had stopped using the product because the builds of my software were being detected as viruses. It was really annoying and i had asked a series of questions on these forums regarding this issue, which remained unresolved. By when will i get a refund? No one is responding, neither of forums nor on live chat and emails.
