Against forgery

Type your question here.My brother had applied online for a job in a national bank. They called him,took 1 test nd 2 telephonic interviews,nd then started asking for money for various bans proceedings like visit from a senior officer, laptop,GST +IT returns,file completion charge,nd other formalities. They didn't ask for all the money at once,they asked for it in time to time with some new reasons,by saying that it's their senior's orders. Since they said that they will refund all the money with the joining letter,nd the bank was also a popular one,so my brother trusted them,nd gave about 3 lakhs. Bt then they asked for more money ,so my brother refused nd asked them to cancel the application,nd start the process of refunding. Bt now,they are saying that they will returns the money in 7 days if given 15 thousands more to accelerate the procedure, otherwise it will take about 2 months. Now I am not able to understand,whether I should file an FIR against them or not,cz they haven't switched off their phones,nd still they are assuring us that they really belong to the bank,nd they will refund all the money. But I don't want to be late,nd lose all the money,just bcz they haven't switched their phones off ... Plzzzzz help me .... Email : [deleted]
