I changed my ad to search only results instead of display ads and google still kept sending traffic from displayed ads, so I now have a bigger bill on something I knew I wound not get a return on. Also I paused my campaign and it still kept running and google still taking my money I have deleted my account now, google adwords does not work for the small business
Re: Billing Issue
That sounds surprising. If you take a screenshot of your account Change History (Menu: Tools and Analysis -> Change History) and email it to AdWords support, along with information on what you've been billed after you made the changes you're referring to here, they might be able to refund you the money if it was genuinely a system error.
