Shopify Has Shut Down My Site and Seized My Funds

I have had a website on shopify since 2018/2019. I’ve been on here consistently throughout my time since then. I have always done the best business I can. Recently they shut down my store because it had seen an increase in revenue and traffic. They accused me of scamming or doing something malicious when there has been absolutely zero proof presented to me. They are currently holding a sizeable amount of money from me currently, $54,000. They have provided no response after I have literally shown every little bit of proof. It feels like they have illegally seized my funds and just told me to beat it pretty much. I’ve provided them with receipts, responses from my community, invoices…literally pictures of my inventory. I need help here and desperately.
