what date stamp did you get? I biked it to chaemg wattana today like a muppet and found all the desks closed, only to be told to go to MTT tomorrow. But I’m reading this stuff now about 60 days from the date you go to MTT
Nothing to do with luck. You can’t be denied 7 day ‘extension’. The denial of a longer extension gives you the 7 days after your visa expires to leave the country. So basically yes, 1900 Baht guarantees you another 7 days
