So on July 6th i recieved an email notification stating; We have received your payment of $1,036.83 on July 6th and this money has been now deposited into your adwords account. Errr, i was a bit shocked so i logged into my adwords account and sure enough there is 1,036.83 deposited into my adwords account. Now i havent used my account in over 6 months, all my campaigns are either deleted or paused. I thought maybe some other adwords advertiser is out 1k and Google credited my account by mistake. On July 7th i wrote an email informing them that i did not fund my account with $1,036.83 and that my debit card does not show a charge for this amount. I logged into my bank account and that money was not debited from my account so it was not initiated using my debit card. Today i received an email stating that i sent them a check which they received on July 6th. They even gave me the check number. I dont have a check number in that range, i did not send them a check and this is all a huge mystery. I know that Google was sued awhile back for 20/30million which was pending disperal of funds amongst the advertisers who were advertising on adwords at the time. Thats all i can think off is that this money is the dispersal fund from that suit. Othewise i have no idea where this money came from. What should i do? Should i ask them to refund it. Should i spend it using advertising? Should i ask them to investigate this further? In 2009 i spent $67k on advertising with them. In 2010 i spent $32k. Is this a refund for invalid click activity, a law suit, a mistake or what? Being a very honest person i just cant see myself taking someone elses money like this. But this is the weirdest shit I'v ever heard of.
