        contacts.each do |contact|
            contact.phone_numbers.each do |phone_number|
                if phone_number.number.gsub('-', '').include?(search)
                    results.push(contact) unless results.include?(contact)
                end
            end
        end

At a quick glance, could it be that you're trying to perform gsub on phone_number.number instead of just phone_number? The error you're getting is because it's not finding number on phone_number.

In order to avoid the "gsub" error described above, it's important to check the 'add_contact' method, specifically the case response block (that comes directly after the response = gets.chomp line).

It must read

phone.number = gets.chomp

and assuming it does, you should avoid that error.
