Aashi Industries Ltd AEC Enterprises Limited Dharnendra Industries Ltd Dharnendra Overseas Ltd why havent these companies been wound up yet 4 Dead companies

These are 4 companies which have been barred from accesing the markets due to the non addressal of investors complaints
Two are Z category one T and one Dharnendra overseas(Old name FLY UP FASHIONS LTD) doesnt seem to exist
such companies are inviting targets for operators to pump and dump
while sebi has atleast barred them and their directors from accessing the markets such shell companies may change names get a compromise order like anil ambani got and come back to defraud new retail investors
sebi should consult the MCA (ministry of corporate affairs ) and wind up these companies
