Caller type: Unknown
A male person called my landline asking for household member. Never gave them any information...I just kept asking "who is this'. He replied a service they were offering a specific household member and said would call back. I hung up. Not sure why telus or other carriers don't block this number on their services. When will telephone companies start taking responsibility for miss use or fraudulent behaviour of their customer's use of their service (this should also apply to mobile and internet providers).
