Address:

West Bengal

I am having one personal loan from Barclays Finance at Salt lake branch, Kolkata, West Bengal. The loan account number is “LC[protected]” For 3 lakhs loan on dated 19/07/2008
Now I want to prepay the pending loan amount and in the regard I have visited to that branch previously and found that the branch has been closed.
For the last 2 months I am following up with them in this regard over phone[protected]. Every time time the representative conveys me that they will get back to me with in a week but not received any update after that. I just want to know what the pending amount I have to pay is and how means to whom, as all the branches in eastern zone is not operating any more. I also have written one email to then in this regard in 3rd September but didn’t receive any response. I want to pay the pending amount in this month. Please advice what to do now.
