i got a message saying that Your account is suspended - We've identified suspicious behavior in the payment activity of this or your other AdWords accounts. To help prevent any unauthorized activity, we suspended your AdWords accounts.
i dont know the reason and still i didnt get any response from adword support
all my related accounts are suspended as well
is it really billing issue ?
Re: account suspended
That's unfortunate. But the reason is clearly provided i.e. the suspicious payment activity.
If you think that's not the valid reason, I would suggest contacting the AdWords support team for more insights on your account:-
