SOrry to be a bit pedantic, but do you mean "stole" as in, they had an issue with your KYC and you didn't bother answering? I've seen it happen too many times, it's just a matter of reading their emails thoroughly.

That's how I was able to finally get my KYC done, I realized the last few emails they had sent me all asked for a PHOTO of my passport, I was sending a scanned document, so I did, and once I sent the PHOTO as they had requested and it wasn't more than 2 hours that I Was able to use my account normally again. Maybe try contacting them once more and see if you can get your issue fixed!
