my trading acconut was disabled for 5 days straigh

my trading acconut was disabled for 5 days straight now(3 business day +2 days weekend), my broker even don't know why, they tried to fix for me, ...  I want to know if this has some relation with the shorties, say maybe they could steal my 4 M shares to cover , or my broker can loan my shares to shorties to cover( even I locked all of them in GTC orders)....
