Well I'll be damned, Facebook actually sent the replacement face cushion(VR Cover).
It took some effort to get it. Initially support responded and said that their records indicated I had already received a replacement. I told them that was impossible and to please provide the name, date, and address they shipped it to. They responded back that there seemed to be an error and they would ship it out asap.
Now of course I do own a VR Cover face cushion, but I bought it from Amazon for $30 and that shouldn't disqualify me from getting the replacement. The pack-in foam cushion was hurting my face. It would be weird and creepy if they had responded with the date I bought or received that from Amazon.
Either way, I'm happy they came through with the replacement and now I can have a normal VR Cover cushion and extra thick each on their own bracket.
