Prime plus package says 600 phone numbers can be viewed, But they dont say u can only view 50 in a month, Cant see 51st in a month and if u 30 in a month, 20 balance will lapse at the nd of the month. Effectively u cant see even half of the numbers in a year. If u call them to know, they will try and confuse you thoroughly.
They will also keep calling you, repeatedly, annoyingly and by dozens of their staff to take assisted services.
