Yes, but was denied after my first request so I called again and they said they'd reopen the "inquiry". Surprisingly 20,000 points showed up in my account a few days after my 2nd call. The bonus said something similar to "20k platinum referral".
I've always had good customer service, but I do spend in the low 7 figures each year. I have no idea if that plays into them just giving me the 20k to make me happy.
