Unable to link Epic account to VIP program

I’ve been trying to link my Epic Games account to my VIP account so I can receive my VIP rewards, however every time I click the Epic Games icon (found here https://borderlands.com/en-US/profile/settings ) & sign in, it redirects me back to the VIP site and doesn’t link the account. I am not receiving any errors or anything either.

I also have my SHiFT account linked to my Epic account and I am still not receiving anything from the VIP site.

Has anyone else had this issue?
