If you have Verizon services (*it will not work for wireless), simply call 1-888-226-0799 and ask them about the $40 promotion. Again, this will only work if you have a Verizon landline. This is a promotion through the mail, but you don’t need the actual letter to get the credit. Simply call the number. Hang up and try calling again if they tell you to contact local billing office.
