I applied for Home Loan from LIC, since the day i have applied i am getting incorrect information from the bank

Agent - Manisha Saini & Rajkumar Saini
Place - Alwar

Issues Faced -

1) I was forced to take the LIC Policies, as per these two people it was mandate for me to take the policy
2) Double processing fees was informed to me

Now, i got a call from LIC ( same agent )stating my loan amount will be reduced. As per them bank can change the amount after sending me the sanction letter, this is not acceptable and i don't think its legally possible. Please suggest.

My Name - Atul Gulati
File Number - 381
Property Details - Omaxe, Bhiwadi City II
