Rogers will not credit you. I just called Rogers to find out why I see these charges on my pay-as-you-go calling history, and was told that if someone leaves a message on your phone before 6 or if you check your voicemail before 6, you will be charged .30 cents each time. Anyway Rogers can get more money out of you they will.
Additional Note: This unwanted phone number shows up on the website transaction record as 416-357-1041 but on my phone log it is listed as 416-802-0447.
