My parents never got a lot of phone calls to their landline until they signed up for Comcast. They had Verizon for years but DSL was aging on their daily usage so I moved them to cable. Non-stop spam calls all day. I had to buy one of those boxes that plugs into the phone line to cut back on the amount they were receiving. This coincidentally started a week after they got Comcast. I am convinced Comcast sells their info or they have data leaking somewhere.
