StashFin — fraud company

I applied for loan from stashfin online they said you are eligible for 186000. They took my documents along with 3 signed cheques. I got a call for a person named jahid hussain on 4th april 2019 stating the amount will get deposited to bank account after deduction of processing fess rs.5580 & gst rs.1004 from the approved amount i. E. Rs, 186000. The amount is not yet credited to my account nor they are replying to chat. I think its a fraud company. Please help me with my documents and the cheques which i have given to them
