I am writing this as a warning to anyone to AVOID linking their credit card with google adwords MAKE ONETIME PAYMENTS. 3 months ago I signed up for adwords for a client. I spoke to an online rep I said we had a budget of 1500 dollars and after that i wanted it shut off, he walked me through the process of creating the rule over the phone to shut off after 1500 was spent. The campaign ended after the money was spent. This month i had a deposit for 500 into adwords. I created a rule to stop it at 500, I logged in august 10th and it had stopped so i went about my life. Look at my credit card bill today and googles site, i have been charged an additional 500 and google says on top of that i owe 560. Apparently regardless of my 500 stop the campaign rule they say any previously setup rule would rerun and since the other rule was for 1500 months ago it overwrote my 500 rule because it had the greater amount. I said how is that kosher how is a customer supposed to know that his new rule will get overwritten by something their support staff setup months ago and already ran. Guy laughed said some things I honestly didnt understand much his Indian accent was so thick I said can you at least unlink my credit card. He said no you cant unlink a credit card from your account unless you put in a dummy credit card, and its true there really is no remove credit card button what the ####? I am now going to call my credit card and cancel my card and file a dispute with my card over the original 500 they took. This seems like a blackhat payment scam rather than a fortune 500 company that says dont be evil im so confused and disappointed at this.
