Verizon will be conducting a door-to-door survey in Waltham.
The mayor's office published the following statement on the city website: "Verizon will begin surveying some customers in the town regarding telephone service improvements. The process will involve Verizon managers contacting existing Verizon customers at their homes. Verizon employees will display their company identification cards and will address any individual concerns. The project will begin this week and will continue until complete within the month."
