My sister applied for a family visit visa and it was refused twice. Both times citing that documents were missing even though the documents were provided during the visa application. One set of documents (originals) are returned and it is present in that bundle. The other set was an exact replica of the original set. There was no way of this document to not be in that bundle. The first time they claimed the whole bundle was missing so it led me to believe the case worker overlooked the documents not once but twice.
Anyway, we asked for admin review which we got refused. The complaints haven't had a response yet and they keep pushing us away from any form of useful info and keep sending the standard messages.
I contacted my MP who is raising this case with the relevant dept but no progress/reply so far.
The deadline to appeal is in the next couple of days and was wondering if anyone had similar experience or any advice please?
(We do not wish to apply again as it's just a waste of our money travelling to visa appt, fees etc if they are going to be reckless with their jobs. I'd rather they set it right or for an appeal. )
Thanks for your time

Best wishes,
