Indusind Bank — indusind bank regarding noc of two wheeler

My bike loan has been closed in month of march 2020 and i didn't get any noc, form 35 from bank (Indusind bank, davanagere branch karnataka), they are keep on telling that it has to be coming from head office, tamil nadu. Representative told me that there is no courier facility at this time u have to wait for a time being, i requested them to send me via indian postal service, but they said they can't do that.
I wanted to sell my bike, without noc i can't do that process, please help me to get noc from bank.

Bank will not loose single rupees from the customer but when customer asks for something they have many reasons to answers.

I wanted to sell my bike as early as possible, as i am paying interest outside, i wanted to stop that burden.
