A few weeks ago, we reported about the issue Indian advertisers were having with Google being able to charge their Reserve Bank of India RBI credit cards. Google was forced to require these advertisers to fax over their credit card authorizations, which slowed the process down to getting campaigns live.
On August 17th, an AdWords representative updated the Google AdWords Help thread saying they are now able to take these cards electronically. Bindu from Google said:
We are now able to charge all such accounts without further declines from the Citibank end. Any credit card that has been declined post August 13, 2009 is a normal decline (the steps outlined over here should assist you with troubleshooting this issue.)
If your credit card is still declined, you may want to re-enter your billing information (outlined over here)
If you have not sent the standing instructions form yet please do so as soon as it is possible.
For all other queries, you will have to contact support.
This was a huge thread with dozens, if not, hundreds of complaints. I hope this is resolved for the most part.
