In reviewing my past bills I found two numbers that were supposedly dialed from my home phone number. One on January 7 to a Fort McMurray number for 15 minutes and then one 13 minutes later to a Red Deer number for one minutes.  Six days later to the same number in Fort McMurray was called for 5 minutes. We were not even home on January 7. In chatting with support all they told me was I was charged because the call was made from my land line. Although the charge is negligible I still would like to know how this could happen.
