Google ads working in mysterious ways

Hi
I have a 2-months-old google ads account set in a 3-years-old google account. 5 days ago I made a deposit and created my first campaign. It worked fine. I removed it as it was just a test and.... since then I can't get any campaign to work, even though all ads are approved. The campaigns just don't run. 0 clicks, 0 impressions.

I've contacted google staff many times during this last week, they don't seem to have a clue what's going on. They say everything should be working.

I would sincerely appreciate any suggestions, as I'm about to give up on google.

Did you try changing your ad? Sometimes editing the ad again helps.

Also check your keywords and bids. Maybe the niche is too competitive or the market is very narrow or limited audience

Any update? What happened to the account?
