Two calls show up on my telephone bill as outgoing from my home number to 613-422-6951 one for 21 minutes ($30.03) and another for 12 minutes ($10.92), and with place showing up as 'OTTAWAHULL'. I don't recall making any calls to this number nor do I know who this is. I do not want to call them back, in case this leads to more billing. Also I generally use my cell phone for long distance calls.

Any ideas on what's going on? Is this a scam which somehow results in these guys making money.
