I can;t submit app update due to incomplete pricing and MS support keep closing my tickets

Question

Hi all,

I am trying to publish an update to one of my games, but cannot submit as partner center is telling me my pricing and availability in incomplete. I have checked and checked and there is nothing wrong with pricing and availability. I can update other titles OK , this is only affecting a single title.

I have also lodged 3 Microsoft support tickets, and all 3 have been closed with no contact or resolution.
