Billing problem with a previous purchase error

Hi, I'm having the message said in the title show up whenever I try to update or download any apps. I've had it happen before, I know it's because of an unpaid balance as that's what it was the last time. Thing is, I haven't bought anything and checked my purchases and subscriptions and there's nothing pending. So I have no clue why it's saying there's an issue with that. I also no longer have a card on file, I had one but it had no money on it I believe but that shouldn't have been an issue either considering again I didn't buy anything.

If anyone could help that'd be great!
