Mollie's comment made me think about one time that I sent an email to customer service asking everyone if they helped such and such account...
Well that may have worked IF I sent it to the correct "customer service" email... BUT if you've ever worked in customer service and with vendors you'll know that many vendors use a typical "customer service" email themselves.
I sent my particular email to customerservice@craineplumbing... Well don't try to email them because #1 they have disabled their email. #2 when it was working they hardly ever answered it, so it may as well have been disabled.
Lesson: When you remember things that bring a smile to your lips- share it.
