Looking for UK solicitor

Hello, we have a problem with some UK online banking company called Wise. We created Wise.com account for my company about 2 years ago and used it without any problems and on January our account got blocked, I appealed their decision, because there is about 20000 GBP in my Wise account balance, after sending them numerous documents they responded to me that my account is closed and they won't send to me my balance. I tried to contact them a lot of times and they said that it's their final decision. I think it is a total scam, I have absolutely all documents, my company is registered in UK and it's fully legit, I'm paying taxes, all my payments came from Amazon. So we are looking for sole solicitor in UK, who could help me in this situation
