As per their confirmation the refunded the money 1499 on 19th nov. Still it was not credited by the bank .I contacted my bank customer support. They are not able to locate the refund with these reference numbers.

I contacted bank customer support. They are unable to do anything for this refund. Their customer support service is very poor. So, they advised me to contact the branch. The branch is also unable to help me with the same.
The reference numbers are.
