Indian Bank — Interest rate in notice board, Appraiser charges and Old age people waiting so long for senior citizen amount

I visited Madhavaram Indian bank this September 2022 for gold Loan, I noticed Interest rate for gold loan in ATM notice board Banner and in outside bank as 5.8% rate of interest but i got jewel loan more than 7% rate of interest and other than processing fee of Rs. 189, appraiser charges demanded Rs. 160 for 30k. I visited 11am but got Jewel loan at 3:30pm. Other old age people also waiting from morning onwards and Assistant manager Lady scold and shouted to old man who waited for so long. My concern is to fasten bank employees, fixed appraiser charges for loan, proper notice board with interest rate and kindness to old age people
