Very poor earning app. Review on Slidejoy

Hello friends i am using slidejoy app before a long time around from 2016. 1st time i use slidejoy app june 2016 after using 2 months i am earn 800 carats and redeem these carats for airtel recharge of 25 rupes after that i am uninstall this app becausewe earn 10 to 15 carats only in a day and for these carats we loose mobile data aprox 500mb in a whole day so i am uninstall this app . After 6 to 7 months later i am again install this after watching the ad of this app on youtube but my issue is same as above i am earn hardly only 15 to 20 carats and for reedem the carats we require 450 for 25 recharge and 2040 carats for 2$ on paypal and i am earnonly 300 to 450 carats in a whole month so for redeeming 2$use this app for 5 monthsand after that redeem only 2$ =140rupes only for these 140rupe first we loos our data aprox 500 mb per day and in a month aprox 15000 mb and for 5 months is 5×15000=75000 mb data so use of this app slidejoy is not profitable so i am uninstall this app again. In this app is given some options for earn more carats like playing games , adsens, downloading apps , servais etc. But in india any option is not working , i am trying to earn carats by playing games but i reach the score whoese given in game for wining the caratsa but no carat is credit to my ac, and i am trying many times to completing servais but every time it is showing that no servaiy is avaliable for your contry
