That's what OP tried to do according to him. He asked about the possibility of account closure because of the inability to do KYC and all they said is he has to complete KYC.
That's what he wrote before the 2 of you made your replies
I’m having trouble uploading a picture, but I just said “If you close my account do I receive the funds” and I got a response of “As mentioned, we require you to complete KYC with your proper details. Please let us know when you wish to do so. Thanks.” I’ve had better reports on smaller sketchier sites where I actually won something
So there is what Razor says and there is what the rollbit support says. One of those 2 appears to give the wrong information to OP.
Just send the deposit back to the sending address and close the account, case close imo.
Umm... I might be wrongly understand it and there is a chance that the one who gave reply as above is other staff, but according to Razer's own reply, he's the one attending to it and he's completely aware of the case, so I think OP simply did not make himself clear enough that he wished not to proceed with KYC [of course, we're putting aside how questionable his reason of "having trouble uploading a picture"]
