Whitelisting /bl whispered players

I happened to whisper /bl to someone at the time thinking whatever happened to them was gonna be left permanent. However, they came back and now i cant unblock them from A)misc menu B)whisper to whitelist I get “a database access error prevented process execution.[no. 1022]” Both recipients on xbox. Now i know this is a goof on my end. I just want either support to contact me for white-listing them from their end or a way to fix it from mine. Thanks 🙂

I have already put in a ticket for this. I also cannot find a number for customer support. Nothing on the support pages help with the problem at all. : (
