In The Name Of Uco Bank Scam

I just got a call from this number and that bastd told me that I need to update my pan card in my account so I told him that I've already done the kyc in past year so he was forcing me so I told him that I'll go to the branch then he told me no you don't have to im on a call and I'm sending you a pdf just open and download and you'll get a paper you'll have to print out something etc. so that bastd send me some kind of apk and the moment I saw i understand and I told him I'll go to the branch again he insists that branch is closed and this things they'll not going to do whatever I told him I'll go to the branch and I'll see whatever will happen and I cut the call this son of wh*re just went and deleted that apk message and after that I abused him just to let out my anger....
