same here it called me and my mom's cellphone. she picked up no one answered. i missed the call and when i called back it was a busy signal at all time. even if i call 6 hrs later! grr.
**Update**
I called the number listed on the website (1-800-542-4400). When I told them I was receiving calls from numbers that traced back to their company I was immediately transferred to "Jack". He asked for my cell phone number and told me my number would be removed this evening to avoid any future calls.
