Are you a fairly experienced Adworder? If not please double and triple check your Ad setup.
As far as the Adwords team response is concerned, I have had shockingly slow responses from them over the last 6 months, 4 days average (with apologies attached). However my last email was responded to within 24 hrs.
Somewhere else AdwordsAdvisor said that the team are changing over from premium ads to Adwords currently so that may account for it.
