China unicom suspension

China unicom was suspended on the NYSE in January and since then I haven’t been able to sell my shares and they haven’t been transferred. As China unicom now trades on the Hong Kong exchange, will our shares be transferred to them or will the shareholding be closed down and sold? I’ve not been able to do anything with them for 9 months, how long does trading 212 usually wait to make a decision on delisted companies? Thanks!
