Hi, my corporate card transaction is not showing up in concur expense, Card transaction tab.

When I accessed to Citi card website and paid, they are all showing up correctly. It is Concur that's not synchronized.  

1 :  5  transactions are showing up as Pending Card Transaction. 

2:  3 Transactions are missing in Concur that are listed and paid in Citi website.

it is taking 3 hours already to resolve this simple issue.

Please help me to provide clear and complete solution.
