Google Adwords Login Issues driving me nuts

Trying to set up anything Adwords or Adsense related on Google is like trying to teach a baby to walk.

While managing Google's My Client Center, the amount of times I've dealt with emails not being sent by Google for Adwords invitations is unheard of.

And don't get me started on the whole "This account is already a login to another AdWords account. Please select a different Google Account login to access this account." mobius loop.

This thread at Webmaster World typifies the sorts of Google garbage I have to deal with on a daily basis.

Furthermore, Google's own Adwords Learning Center, at least for me, appears to have completely wrong details on how to link accounts. It says it can do it easily by:

1. Retrieve your client's AdWords external Customer ID and account password (which establishes your client's permission to link the account to yours).
2. Log in to your MCC.
3. Click the Link existing account link above your client accounts table.
4. Enter your new client's Customer ID and account password into the appropriate fields.
5. Click Submit.

However in my "My Client Center", there is absolutely no option to enter the account password and when I click submit - nothing happens. No email to the client, no notification in their Adwords account - nothing !

I'm nearly fed up with the then I get support people who don't even know what they are talking about and sent generic mail merged responses. If only they realised that if their systems were usable and they answered their support queries, they might actually get less of them.

No wonder advertisers are moving to Yahoo. Pretty soon I'll be one of them.
