I am a C&A member and browse the RC website daily (a little dreaming to get me through the work day). I've never had anyone from RC contact me. However...
I started an account on the Carnival website a couple years ago and received a call from a Carnival customer service rep later that same day. Apparently, I "requested a call for more information." I was not aware that I had done that, but I said that I did not need any information and they never bothered me again.
