Adwords credit overdue

I have used too much on my campain. My voucher was for 75 dollars and I have spent 129 dollars. How can i prevent google from taking the difference from my credit card ? If i load another voucher, will that prevent them from accessing my credit card ?
Please help ! I am desperate ! I need a sollution to prevent them from accessing my credit card !

 

No such luck. Vouchers are only good on new accounts. You won't be able to drop in another.

Best way to look at it: You're only out $54 instead of $129. Hope that AdWords generated some other profits for you.

 

There is another kind of voucher that works on all accounts.

 

If you have a voucher that works on all accounts, plug it in quick. It might work, since they usually bill you once a month I thought.

 

This is my problem ! I don't have one ! Where can i get one and how much does it cost ?

 

I have no idea, try the BST section but I haven't seen one of those for sale in ages

 

Nop, nothing there, damn, i really need a voucher !
