The phone company is a master at getting us to buy services. They sell your phone number to telemarketers, then sell you caller ID to thwart them. In round two, they sell services that block caller ID to telemarketers, then sell you a gadget that won’t allow blocked calls to ring through. Don’t play this ongoing game. Get the basic package, skip the frills and save yourself $100 or more per year.
