Hello admin and staff! I bought $15 pack and received 5 DR & 5 RR. Thanks! But 4 of 5 RR still does not work. Could you fix this problem?

This is not the place for support tickets.  Create a ticket from inside the members area.

As for whether your rented referrals do anything or not, we have no control over that.  If, after several days, they have not clicked on a single ad, they will automatically be recycled.

Thanks for the useful response, dear moderator.
