Not secured and benefifical banking app. Review on Chillr

Chillr is the app which provides the digital payments.Recently I saw a advertisement about chillr in the google.In that advertisement they told that the refer and earn.And they provided a referral link also.I installed the chillr application in my redmi phone through the concerned referral link.And created a account and linked my bank account in the app.After the installation I did not received any referral amount in my wallet.I understood that the app is totally fake.And I referred my friedns in the app.I referred my friends in the whatsapp with a referral link.Thwey also installed the app through my suggestion.But they simply scold me that the app is foolish app and useless.Then I feel shame for the app.From that time onwards I never referred any of my friedns and simply remov ed the3 app from my phone.Now iam feeling no tension.Before deleting this app, we feel that the money fro referral is comes from the website or we lost our money.
