Anyone else not getting any answer from ratings forgiveness?

I’ve sent in a couple of ratings forgiveness requests recently and it seems like they’re either taking forever or you just don’t get any response back from them. Are they just really backed up? What exactly is excessive requests? is it just more than one per day if you do put in one more than one per day then they just ignore it? just seems like lately it either takes forever or you get no answer back. Anyone else going through this?
