Itune account issues

I have been subscribing to Pandora for years. Orginally I subscribed through my older IPad. I have added Pandora to my new and improved Ipad, only to discover that I can not up grade the Pandora on my new Ipad. Error message giving "Your Pandora account does not match the iTunes account that you are currently logged in with....".

Did I mention that itunes has not had issues with billing my current itunes account.

I have been trying to contact itunes support - but can not talk with a human being.
