lucky draw scam

We ordered a watch from naaptol, we received it after some days every thing is ok , but one day we got a call they said,"we are calling from naaptol you ordered a watch" (they even said model name so we trusted) you won 10 lakh in lucky draw. First they said to send bank details so they can send to our account no. we sent image of bank book then they said there is a tax issue you should send 25000 to us so we can send remaining money along with your 25000 , then I got a doubt so i said take 25000 from that 10lakh and send remaining 🤣🤣 but then they tried to convince us and said,"we talked to our head so we will adjust some money from our salaries so you send 8000 " like a fool we trusted and sent 8000 then they called again and said," sorry the tax increased you should send another 15000 then you we can continue" at that moment we understood that is fraud call so we said to return our money then they ended call and no answer. From this experience what I understood is , mysteriously they had connection with naaptol or naaptol information or else how they can say what company model watch i ordered from a sealed package. Thats it be careful.
