Reps don't always contact advertisers. What sometimes happens is an advertiser has a problem, calls Google support, and they tell the advertiser that they have a rep and put them in touch with them.
I'm an affiliate spending £20 - £30K per month on Google. I got my rep last week after pestering them for ages and ages. I think the reason I didn't get approached was because I have 12 accounts and only a couple have more than £3K/mth spend. However, one had that level of spend for at least a year. I'd say send an email to AdWords with a list of your accounts and explain clearly why you need an account rep and you should get one sooner or later.
Cheers,

Maybe with the new control panel they'll start to realize what folks like us are worth. Many of my clients are on Google because they came to me looking for traffic and I sold them on my Google adwords services. Without me, they'd not be on Google. These same customers are NOT advertising on Overture simply because I haven't had the time to get set up over there. When I do, we'll be spending the same amount at overture - but overture does recognize my sum spend as being a decent amount (not that it makes any difference really. It would just be nice to speak to someone knowledgeable in my industry when I have a question once every 3-6 months).
As an agency there is no "collective" bargaining position. Each client is viewed on it's own merit.
Porbably not a great analogy, but if you were a member of an exclusive drinking establishment and only sat at the bar pestering the staff but not spending money on the drinks, eventually your membership would be revoked, and quite rightly.
Although Google have been recruiting like mad there are still not enough people to go round for all those wanting to sit at the bar.
Service levels I have heard can vary wildly, but that is ultimately down to individual employees enthusiasm rather than a cast in stone policy and that would be the same in any organisation.
As an agency we are very protective of all our supplier reps. although they are happy for us to give their details to clients, we guard them dearly.
