Sorry but I have already requested a refund from my side through my debit card financial institution as I was not happy with the plugins missing cities, post codes and some countries were placed as areas. It is missing registers (cities and postcodes) in many countries. I can't invest my own time to figure this out and fix it. I am building a worldwide marketplace with Sellacious which I really like it and the plugins were to help me with the Geolocation but unfortunately it was not what it was supposed to be and did not solved my problem.
I will update Sellacious and leave it as it is so the customers when registering enter their address completely by typing each information.
