Problem with "clean_number" refactor

event_manager.rb

	def print_numbers
		@file.each do |line|
			number = clean_number([:homephone])
			puts number
		end
	end

	def clean_number(original)
		number = number.delete(".").delete("-").delete(" ").delete("(").delete(")") 
                #There must be a shorter way to deal with this..?

		if number.length == 10
			# Its good, do nothing
		elsif number.length == 11
			if number.start_with?("1")
				number = number[1..-1]
			else
				# Turns digits to 0's
				number = "0000000000"
			end
		else
			# Turns digits to 0's
			number = "0000000000"
		end

		return number
	end
