Blue Dart review by Satish kumar

I got an option of contacting customer on a given number. I called them they told me that I will get a call who will guide me to get the number of delivery boy and they told me that my parcel is in pending state and if I want to get the parcel I need to pay Rs. 2 as service charge. And they send me an app on WhatsApp to install through which I have to register a complaint and then I will get a call from delivery boy today.but when I installed the app my account got debited with all the amount I had in my account. Please see what's happening here. I just installed the because I had faith that this is from bluedart. Please check on it.
