I have adwords account and pay with my mastercard. It's run for 3 month. After that, my card over limit and my impression in adword is "0". I pay my card, and no change with my adwords. I will change other card (with Visa) in my adwords account, but google decline my card. Can I use my card for adwords again? Thanks
Best to contact Google adword support. They will reply within 24 hours. Most likely you have a bad card status on their end.
never expose your card number, it is a problem with your card or payment related to google. you can contact google and get is sorted out, if legit.
