I also submitted a customer service request awhile back (a week or two) and did receive a response via e-mail. My feeling is that the folks that manage such things aren't staffed for a very large organization, and so patience is required...and possible persistence.
I'd encourage you to resubmit your request, if you haven't already, as it may have been inadvertently deleted, missed, been blocked by a spam filter, etc. Likewise, perhaps the response was similarly lost due to a typo, filter, etc.
Unfortunately I can't seem to pull up my customer service response, or I would try to put you in touch with a representative. If I can find it, I'll contact you via PM.
