scammer pretends to be police

someone called me and told I am from aarong we have made a mistake someone has scamed with us few hours ago and we filed a complaint about her and her last number is similar to yours so we accidentally filed against your number a police officer will call you and He called me and said that my bkash account will be freezed for this complaint if I want to open my account I must give them the pin from my messages so I gave them after that my account was not working and then they told me I could not reopen my account I must go to my nearby bkash agent and tell them to send 33500 as send money and said my account is off so the send money will not be successful but a massage will appear by which I can reset my pin number After that I thought something was fishy I tried to reset the pin number on my own by face verification and it worked.A big scammer.
