scam alert online casino agent

This number belonged to my father. Somehow, this scammer registered that number in his name and opened a bKash account. He is also allegedly involved in online gambling as an agent. On 29.10.26 and 07.11.26, I mistakenly sent 6400 Taka twice to my father's bKash number. When I contacted bKash customer care, they said this number belongs to him and when I called him about the money, he said he would inform his younger brother, who has not returned the money. He repeatedly switches off the SIM.
