I called 636-223-8467 back from a land line.  The recording said they are "Merits Customer Experience" doing customer surveys about products and services.  They do ffer an 800 number to be put on their 'Do not Call List'.  The 'Opt Out' registration does not cover surveys if they aren't selling anything.

Just received a call from this number.  Didn't recognize the number so I didn't answer. No message.
