Bitstamp is holding my 100 k and it doesn’t allow me to sell it

Hi, I'm creating this topic because the bitstamp exchange robbed me of over $100,000 (currently it's 85 due to the drop in value, but still in Poland this amount of money allows me to buy a decent flat). I have been fighting them for over a year to get my funds back, they are currently asking for me to do a wallet signature, where after doing it they suddenly can't open it for unknown reasons, although I did everything right, so I sent them screenshots to confirm. Please bump this post, maybe someone from bitstamp management will notice.

By the way I posted this for a user named SlippyJerry since he is desperate and doesn't have enough karma to post.

From SlippyJimmy:

I’ve transferred my funds in 2021 to this exchange from old cold wallet with LTC that I had.I gave them my personal details, papers, birth certificates, etc.After this they blocked my account and funds withdrawal.So they decided to ask me for wallet signature. I did this and they told me that they can’t read this signature.And want to have screenshoots of how I’m doing it.Since then I don’t have any contact with them.
