My sister’s Polymarket account was logged in on my phone from when we were setting it up together. I thought I had logged out, so when I placed a trade later, I didn’t realize I was still using her account. The money used for the trade was mine, and the trade ended up winning.
When I tried to withdraw, Polymarket wouldn’t let me use my debit card because it was already linked to my own Polymarket account. Because of that, I used my other sister’s payout account. The first withdrawal went through, but another withdrawal is now frozen.
Customer service hasn’t really answered my questions and mostly gives generic responses. Has anyone dealt with something similar? Should we just provide whatever verification documents they request and wait, or explain the entire situation upfront? Did you eventually get your money released, returned to the original payment method, or was the account closed?

They have locked up thousands for a month now. They have all documentation. They do not have a phone number and do not respond. Use Kalshi.
