Help To Remove Avangate Account / Remove Billing Details

Hi guys,

I'm already using Bitdefender Total Security 2015 and I'm very happy with this antivirus. But something that I notice after the checkout is that the option Continuous protection was selected, and that implies that Avangate store my billing information, wich includes my credit card number. I don't want my payment method details stored with Avangate, even if they disable the auto renewal. I searched the topic on the Bitdefender forum and there seems to be a way to remove my billing information stored in Avangate unsubscribing the Bitdefender purchases from the Avangate database. I don't want my details with Avangate anymore, so how can I delete my avangate account?
