How to get Amazon Balance.

I used ads on amazon which I was supposed to pay off after a certain period. And I had a card already linked on my seller account for payments of such things. But then after that period I forgot to pay it off and my account was put on temporary hold until I paid the ad balance. So now I had no way to check it since the account was blocked everywhere other than the help section. The card I used never has money and I transfer money on it when I’m supposed to pay for something. I reached out to support to ask what my balance is and I’ve been taken on rounds yet they always try to deduct money from that account. I even told them they have to tell me my balance then I can add it to the account for them to deduct and nothing. They never sent a statement or anything for me to see what I owe but they usually send bank details, how am I supposed to know what to pay? Do they usually withhold that kind of information because I feel like they do.
