I am using the chamet application for 8-9 months and at first it gave a much time to talk with strangers and 12 cards per invite and the cost of the diamonds were also fine,but now all the prices are getting higher than expected so i think this should not be happened,so i would suggest you to please give some relief in the prices and some free features also to all the users if you can't provide then at least ro you regural/daily users.
