Sometimes - exceeded your budget....

Hi all, this is my first post here but I'm reading this forum from couple of weeks.
Please explain me.
"You have reached and exceeded your budget. "

Completly don't get it. I know it's mean probably account is banned but I don't understand sometimes why.
I created arround 20 accounts, usualy I can bring them to live but not always. Sometimes after test campaing is working fine, I'm adding second campaing different domains this same budget and keywords. And one account is banned after minutes second is working until funds are gone ...

Why ? I can't find connection between bans. Today I lost second voucher this week (each has over 100$), so it's painfull. I don't have many of them in my pockets.



Any idea how to get these accounts back? Cards used for these accounts creation still works.

it means that you have reached you daily spending budget.

You have to wait until tomorrow or increase your budget

nope. I have budget set to for example $90 and I don't spend single penny. I have $120 on my account, or at another one I have daiyly budget $2 and I have there $100, not single impression or click. It's usual means they flagged your account, becouse ... I don't know why. I'm waiting at one account from 3 days without a success.
