Account is disabled in iTunes & app store

I disputes a charge with iTunes because I meant to cancel a trial membership and didn’t do it on time, so they put my account negative - and I’m not sure if this is apples way of being petty, but since I got my dispute whenever I try to use an app (one of the many I HAVE ALREADY paid for) I get an error stating “account disabled in App Store and iTunes” and the error sends about seven times after clicking okay.

(You see why I’d be slightly frustrated)

I’m just trying to use apps I’ve already purchased and not sure how to resolve this issue.
