The orders won’t be processed if there’s not a buyer - based on the amount you’re trying to sell, there just simply might not have been someone wanting these quantities of stock (whether this be too many or too few).
I’d imagine a lot of people are trying to exit their positions in this stock, and the amount of people able to buy is extremely restricted which will make the process even more difficult.
I completely understand the frustration around customer service response times and hope you get a response soon but feel it may be along similar lines of what I’ve posted earlier in the thread.
This borders on the debate on previous threads as to whether Freetrade should be there to alert their customers of all changes that could have implications on their holdings - personally, they’re a platform to facilitate the trades and not to help track changes that may impact individual portfolios. Opinions may differ.
In terms of what can be done in this situation, I say it would either be to continue to try and sell the stock in app, possibly even smaller quantities at once to try and clear some of it. I do hope you manage to exit your position and you get a response to your query from customer service, but I fear that won’t automatically mean you can sell.
