Reserve Bank Of India [RBI] — Regarding processing fee

Address:

Bhopal, Madhya Pradesh, 462023

Dear sir
I have taken home loan from sbi bhopal the executive mr. Sanjay nagchandi told me that processing fee is waived. But after loan disbursement rs.8050 was charged to me. Now the same executive is not picking phone and also not doing any solution for charge.
Sir it's cheating by the sbi and it's executive. He is not receiving the phone.
Kindly see the matter urgently.
