The app sucks. Been redeeming diamonds at a satisfying rate. But lately, it's changed in the face that you redeem high diamonds for little amount of airtime. The exchange rate is bad and it not good. I want it to return back to the normal. We struggle for nothing. Am deleting soon and I urge every one aspiring to try this app to disembark. It's currently a waste of time unless it it taken back to the way it was. We waste a large amount of data to get a smaller amount of airtime. Not fair at all
