I have received an 'bill_update.apk' file from a WhatsApp number 7772812721. It has kind of the same dp as MPEB but a little smaller. And the call said "apka bijli connection m 4000 rupay zyda lagne lagega agar aap abhi ye ni file kholke bill update nahi karoge toh" When I asked " bhaiya aise ek ghanta toh do, dekhen toh kya dikkat hai" he replied, " madam, itna time ni hai isiliye toh ham apko call kar ke bol rahe hai" Has this happened with people before? Is the number valid? Is this scam?

I called 1912 and tried asking, they said "hame ni pata ye sb, office jake pata karo"
