cybertchair review for Pushdaddy WhatsApp, Live Chat

In listing page it is very clear that app is free for development store only. Noone can offer free software. It requires huge amount of work as well as server cost which does not come free of cost Respected Sir, Whatsapp is 1000 billion dollar company. they offer whatsapp free to all. in return what they get?? We all have become sales target for whatsapp and they push marketing msg and get money. we wont do any such thing ever to our customer. so we charge little to manage server price. Remember, if you get something free then you are the product.
