There has been quite a bit of documents passed on to the proper agencies from pilots, enginerring log book pages etc.
Thailand and to include the FAA would do best to act on these reports.
Once the next accident happens the lawyers will have a field day with proof showing that pilots complained of these issues prior to the fact and nothing was done.
This is much worse than some USA company not doing the required enginerring work on time,this involves total disrespect for any and all flight duty times, Mel compliance, 3 engine takeoffs, threats and intimidation from The Indian manger, either fly or go home.
As he stated he has many Filipino and Indonesions pilots to take your job at half salary.
