Got a call from someone claiming to be my friend Alvin Tan, calling from this number (8193 5672) with no + and the person knew my name. He claimed to be my long time friend but i got no recollection. He asked to add his number to phonebook n whatsapp, asked to meet up when free. Next day, he called and said he asked whether i am familiar with dbs account. He said he is facing problem logging in as he lost his phone. I was wary of what he said and told him he should go to the branch to ask instead of asking me and i blocked his number after that as it raises alot of red flags. Then i googled and found similar scam methods reported as well.
