App Developer's Struggle with Prolonged Review Process and Lack of Support

Hello, sorry. I'm not sure if this is the right channel, but I'm desperately trying to get some movement in the app review process. I'm still stuck on 'waiting for review.' I submitted my app for review a second time on March 22nd, after having already submitted the same app on March 2nd. Since then, it has been in the 'waiting for review' status. I've called the support in Germany five times, and each time, I receive the same response:

  1. 'It should only take 24 hours.'
  2. 'We can only forward it.'
  3. 'If you don't receive a response in two days or get an email, please contact us again.'

Is there any way to get a more concrete answer than 'it should only take 24 hours'?

Thank you very much.
