Chris Freytag Health Blender Travel Mug

Question

I just purchase the Health Blender from QVC. Love it, except that I cannot get the top off of the Travel Mug. I've tried everything short of dynamite! I tried the hint given in the manual of soaking in hot soapy water. Didn't work! My husband can't even get it off and he's no ninety-pound weakling! I hate to have to send the whole blender back to QVC as an unsatisfactory product, but I want to use the travel mug.
Any suggestions? Or can you send me a new mug?
HELP!
