For bags that are delayed, they will reimburse reasonable expenses accrued on the basis of the purchase receipts that you submitted . That's why it's very important to obtain, and keep, receipts for the essentials that you buy.

Only if there are no receipts, or it appears that the receipts related (partially) to unnecessary items under the circumstances, will they offer a lower settlement.

Without knowing what your exact scenario is, I'm not sure that there is anything further we can advise you. Email is not a manner by which such reimbursement requests can be lodged, and if you are in dispute regarding an open case, you should have the ability to add further notes to the case.
