I would have suggested contacting your MP, but I feel that approach is now overused. More people are aware that it’s an option, and with the increasing number of applications, it’s becoming a routine step which may be reducing its effectiveness. In the past, it felt more impactful because it was a relatively unique request. MPs were contacted less often, and when they were, their involvement seemed to carry more weight than it does nowadays (at least in my opinion).
Anyway, if it makes you feel a bit better, many of us from March are stuck in background and prohibitions with timelines almost similar to yours.
