I Lost My Balance on Bayspin Without Warning

I put ₺490 into the Bayspin site, and my balance went up to ₺220,000. They told me there was a daily withdrawal restriction of ₺100,000, so I took that amount out. They also indicated I could take out the rest of the ₺120,000 the next day. But when I logged in the next day, I was surprised to learn that the rest of the amount had been wiped. They said it was because of a "wagering rule" that the site has. The difficulty is that the platform doesn't say anything about this rule. I looked over all the phrases very carefully, and there is nothing that backs up their argument. I sought for help through live support, but they didn't provide me a clear explanation. It seems unjust and wrong to have my pay taken away without warning. I just want this to be handled correctly.
