Re: How Can Refund My Adwords Balance My Card?
Thanks for posting! At this time, the only way to request a refund for a pre-paid amount is to cancel your AdWords account. Once you do so, any pre-paid balance will be refunded. More information can be found here: http://goo.gl/KIM1dD . You can also request a chargeback with your bank - but in that instance your AdWords account would be suspended.
I hope this information is helpful.
