Recently I have noticed that there is an unauthorized transaction on my credit card.
I have not authorized any transaction through that company.

Here are transaction the details:

15/02/2009 24736929046313184596710 EPOCH.COM*MANSTERMED Rs. 2, 526.69(DR)


How do I get my money back from them? The money was shown in Indian Rupees (INR 2526.69 = $50 approximately)
How to stop them deducting my money ?

I want to block all the trasactions (in future) from that company on my credit card.

Thanks
