Liquidation/ Bankrupt Companies

Unfortunately I have some stocks/companies that have gone bankrupt. Obviously this is part of the risk of trading/investment. However some of these have been left in limbo for months and months, some T212 have made view only, it is impossible to get rid of them to ofstet against capital gains. I have been awaiting liquidation for quite some time. Can you look into this, in particular now known as : LLFLQ , ARVLF, SDCCQ
