With this, I will only write was has happened with me with a scammer using halobca name as a cover, who knows this will help preventing to someone else. Yesterday I got a call with the number of 500888 where the number is nearly similar to HaloBCA where its number is 1500888, at first I was suspicious but not fully suspicious because the call was using VOIP, the man said with his words "I want to complain because there's a unreasonable 4 times transaction with your credit card" I was asked if the credit card is in my possession and luckily I can access klikbca where I can check my credit card transaction, from here I wasn't yet suspicious ones again but when he told me to check my message now that's when I get suspicious. I then told him that why would you need to scam with a calm voice because I know that this is a waste of time and my energy then I hang up the phone. The message looks like this

BCA: KODE OTP {nomor} transaksi bukalapakcom, IDR 1.0022.359,00 berlaku 5 menit. jgn beritahu kode ini kpd siapapun termasuk yang mengaku dr BCA

this was sent to my message 4 times, I tried to do the right thing by reporting this to Bukalapak but the message wasn't strong enough to make a case, also I sent a letter to HaloBCA as well.

What I learned was when someone using VOIP as a call and try to be an institute like BCA, that will be my red flag and always check the number on internet you might find something.
