Not very useful

Recharging a Cuban mobile via the app doesnt work as smooth as on the website. I didnt get a confirmation email and I could only choose between two amounts. My recharge history doesnt exist, only the phone numbers without the date. Also, I was asked my login password to confirm the credit card recharge and not the security number on the card. What about security? The website works fine! Why doesnt the app?
