If you are asking us to review a case, the officer that dealt with it will check to see if they can resolve the matter by providing you with some further information. If they cannot, they will pass your form to their manager so that they can respond.
The manager will consider your complaint and write to you with their response, making clear which parts they do or do not uphold, giving reasons for their view. They should also make clear what further action (if any) they intend to take with respect to your complaint.
They should provide their response within 28 calendar days. If they are unable to respond fully within that timescale, they will let you know when they will be able to.
