I'm sorry to hear about that. However, Google Ads is very difficult and confusing to use so I understand. Clever Google Ads can help with your confusion though. The app will help you with keyword bidding, ad optimization, and certified Premier Google Partner team will be there to answer any questions, and make sure you are not overpaying for ads that have a high bounce rate. The app is free to download and you can find it here.
I hope this helps!
