Batch ID missing for Campaigns

Although all of our Campaigns are ‘delivering’ there are absolutely no impressions recorded for today even though it is set at the highest rate for CPC it has ever been set at in an attempt to bring in orders. I have tried to contact Advertising but can’t get the email to go through without a Batch Number. No amount of searching or Googling can tell me where to find this. Can anybody help please? TIA
