HDFC Bank — loan & dd charges fraud

I am customer of many banks. I have never ever faced any major issues with any bank. I was of the view that hdfc bank is the best bank and also since its near to my house, i had opened bank account with hdfc bank.
Recently i sold a property n deposited my sold value in hdfc tatanagar branch bangalore.

First part (Loan fraud)
When i called hdfc for plot loan, initially they tried to get my attention towards them, they told no processing fee n i proceeded with it. This was around 2018 dec. I gathered all documents and gave it to them after many iterations, finally my side i gave all docs around early feb 19.in mid feb, they had called me and asked for processing fee of 10k+gst which came around 11800rs. But they promised everything is included & lawyer fee is also included in this. But again when i went to lawyer office, they asked me to pay rs 2500 for the lawyer. They promised no charges and charged extra every single time.
This entire process took more than 6 months for them to complete n to get my loan even though i submitted all docs around mid february. I resubmitted all docs again and again. I was seriously frustrated by the bank already
Second part (Dd charges fraud)
When i was taking dd to my seller which was around 24lakhs, the bank didn't give any prior information that these dd charges mount to 13k+, i even asked them is there any charge that i can fill in the sheet. They told no charges to fill n also i met manager who also didn't tell anything. The dd form also didn't have information about the charges. Normally all banks form have commission charges section where we fill out charges, this bank neither have prior info or had this charges mentioned in the form. On top of that i even asked them. The branch is tatanagar, kodigehalli bangalore hdfc branch.
The deduction is done around one week after the dd issued. How will the customer know this & from where the charges are applied. When i asked this to bank manager, why didn't she inform me at the time she is saying the bank doesn't educate the customers and customers should read and kind of byheart the charges...
13k is not even average salary of a daily wager. For giving my own money the bank has charged 13k. How is this fair???
Just to print one dd paper they charged me such a hefty amount.
Is this really fair??

I need my money back??
I will definitely not recommend any one for this bank ever...
I hope via this forum, i can get some justice and help.
