Unfortunately I do not have caller Id in my cell phone. I did not know I could not dial *69. I do not think there is any caregiver association in my area (I live north of Toronto). I was so scare after the 2nd call. I was just making and image in my mind about what could I have left in the front yard that will point out my location to these people (sometimes I leave my Quad stroller in there)... A few days after telling a fellow provider about this incident it sound right to post it in this Forum where is the only place I can reach more providers (just in case you any of you find yourself in a similar situation)...
