RBL Bank Credit Card Fraud

I saw an ad on Facebook to get an RBL credit card. When I submitted my information there, I received a call from someone claiming to be customer service saying my credit card would be approved. He gave me a link to click and apply. We talked a lot on the software, but since I am from the computer field, I knew. So when he asked me to download an app called RBI sorry RBL credit card.apk, I realized it was a scam. So everyone, be careful and stay safe from this.
