I beleive that Cougarhositng is reselling for monsterhosting.ca or some part of that company, at
http://www.monstercheckout.com/ you can see the same phrase that she used in her ad. Also the customer support numbers are the same.
If the company that gives her support for being a reseller claims that, I would think that she can make the same claim. Her support team most likely does actually support 1000's of customers.
