Vinted app, Online Marketing Place review: The company holds my earnings

To whom it may concern,

Hi. I started to use the vinted app which is an online marketing place on December 2022. At first few months it was fine, but about March 2023, they asked my ID or passport for identification verification. So I sent them my ID, Address proof and bank statement. But they began to hold a part of my earnings about £140,

Till then it's 5 months that I could sell nor buy through this app, and they are holding my money. I have sent them requests for resolving the issue via email, text messages. But it didn't work.

I really like to continue my activities there.

Please help me to resolve this issue.

Regards
