google info must be verified from authentic sources, for an example if people want to know baggage policy of airline travel, it must be from airline website,
People in the grp can provide their travel experience, hotels, sight seeing, currency exchange, transportation etc,
relax and enjoy your holiday, try on 30th aug to fly malaysia as I see no papers are torn out, just water erased stamp, I think you should be fine, if not you have option to flyback home
If you are flying back to India or home country, go to embassy to get emergency doc to fly back,If this is just thailand immigration stamp erased, they might have details in system so you may not have any issues, all depends on immigration officials
