Indian Overseas Bank — Money debited excess of loan amount without intimation and delaying to return

Account number- [protected] loan accnt- 1298 Branch- IOBA0000228.
Last friday 27/10/2022, around 148000rs debited from the account for loan repay. Which was not intimated before and when i went before 10days to settle and renew, Due to Agri officer was not available. Suddenly the money was detected. When we enquired branch after detected they said manager only can credit but he is on long leave so we have to wait for 5 days. I complaint the same to regional officer. He have commited the excess amount will be credited back at 28/10/2022. But its not yet received(30/10/2022). I tried to complain in IOB portal. But that was not user friendly. The portal was not allowing to submit the complaint as special character not allowed. I tried to even remove the dot in sentence, Then also it was not allowing. Never experience such bad service.
