Hi I registered an adwords account and tried to verify account with my CC the account had been verified and there was no problem with my CC and I checked my bank online statement and saw that google had charged my CC 1$. after that, it said that I had to start my first campain and deposite atleast 10$ in my account to activate it. I tried to deposite 10$ in my adword account with the same CC and I had enough funds on it but google declined the CC. it`s strange for me. What is the problem?
Have you tried contacting your credit card to check they aren't blocking Google? Unfortunately putting small amounts onto a credit card is a tactic used by fraudsters. They do it to check they have access to a credit card and then they sell on the details. So credit card companies sometimes block accounts when this happens.
