I ask for your assistance because, dispite correspondence with Polish
Adwords support it failed this way to obtain any information beyond
the standard ones and, and in the current situation we are very
concerned...

We have (as SEM Agency) several Adwords accounts linked to one My
Client Center.

A few days ago we ware trying to create another account and add founds
to
a new campaign, but our card was declined (previously acted without
the problem). So we've contacted with support (in parallel
sending money transfer, so not to waste time) to explain
and received the answer (translated from polish):

"It came to our attention that your Google AdWords account
xxx-xxx-xxxx does not comply with our terms of service and
advertising policies. As a result, your account has been suspended,
and your ads will no longer appear on Google. In accordance with
Terms and Conditions, Google reserves the right to
stop showing ads for any reason."

moreover, in subsequent correspondence trying to figure out the cause:

"I also regret to inform that the whole account," My Clients
Client "has been suspended in connection with this all AdWords
accounts
managed by "My Client Center" will be inactive ."!!!

In any case, there has not been on our part to deliberate breach
Google Adwords
Rules. It is possible that unwittingly we've made some mistake,
however, does not in any way we can concluded that, because support
does not want us to say anything beyond that account may be suspended
for "any reason".

I understand the need to ensure that the Adwords system safty but
suspending
ALL accounts connected to My Client Center, specialy without
any warnings or later explanation seems to be
very drastic measure, and it seems that it should be
used as a last resort, for example
on the issues like fraud, or law breaking and nothing that was not the
case.

So please kindly for assistance what no we should do in order to solve
this problem and
to restore MCC and other Adwords accounts, because I think
that the obvious is what means for the SEM agency and its Adwords
customers, to suspend all accounts and be banned from Adwords :-(

Yours sincerely, and thank you for helping advance
