We will definitely take a look at this and see if there's something we need to change/fix. You should be able to set your VIP rebill to a specific card that shouldn't change regardless of what card you're using for purchasing.
I have sent you an email regarding this. In the meantime, if anyone else is experiencing this issue, please email customerservice@vsmedia.com.
We'll post on this thread if there are any updates made.
