Beware of google ads campaign

Becarefull of google ads. They say you get one ad free and then take money from your bank account and your bak tells you it is a 12 month debit order. google does not have an complaints email adress, and there help and support is non excistent. I just lost my money and are worried for the next 11 months. I will have to close my bank account. Worst of all, days after trying to cancel the ad, the free R 600 appears in the closed account.
