There is problem in payment process 
Firstly the initial amount of 4000 + is paid
Like itz your payment 
Then remaining amount is done in installments like
They told me it will be deducted only when the course is completed and you are placed 
But after 45 days the second bill is here
After that they told me
No there will be one installment after 45 days after that there will be no bills until you get placed and complete your course 
But today after 25 days there is another bill to pay
Now I am saying 
That you told me something 
They are not reacting properly 
Sometimes say ignore the bill sometimes say you have to pay 
What kind of fraud is going on here
