I have received a auto mail from SBI that my loan is closed and the same confirmed from customer care. Now the issue is in Novemver 2023 ECS had HIT to my account and bounce. the same has affected my CIBIL. I have mailed to GM Customer and Branch Manager Mail ID but no proper response from Brunch manager. Now customer care is asking to visit to the home branch to stop the ECS mandate. For job purpose now I have posted in Kolkata and not possible to visit to the home branch. The same has highlighted in my mail and customer also. No proper response in this regards.
