Disappointing PMI Customer Service

Last month, I needed to get some information from PMI about OPM3 (Organizational Project Management Maturity Model). I wasn't satisfied with what was published on their website so I composed an email and sent it off. I received a confirmation email stating "Thank you for contacting the Project Management Institute. Thank you for contacting the PMI Global Operations Center in Newtown Square, Pennsylvania, USA. A Customer Care Associate will review your request and contact you within three (3) business days." I was even provided a ticket number. So, I waited 3 days. ...and waited. ...and waited.

Disgruntled and disappointed, I called them.  I was routed to "general" customer service.  After looking up my PMI membership number, the service representative couldn't answers my questions so she routed me to the desk of the person in charge of OPM3.  I left a voicemail about having questions about OPM3 and left my contact information multiple times.

And now I wait some more.

I'm coming up on 2 weeks and nobody has contacted me.  I feel like PMI is more interested in collecting membership dues and selling products then serving those who have obtained and maintain their PMP certifications.
