deny updating a hidden ref

[tonyzhao-jt]

Hi, i need to remove some sensitivity data from my repo, and use BFG for this for the moment, but now I encountered

 ! [remote rejected] refs/pull/1/head -> refs/pull/1/head (deny updating a hidden ref)

Anyone knows how to get some support from the Github to help me erase them?

I just found it could be done here:
https://support.github.com/request/remove-data?
Thanks at all.
