You told the embassy in Hanoi that you were in Vietnam on a TR visa and now you're in Bangkok on a TR visa... 🤔
Did you already have a valid tourist visa for Thailand and left Vietnam shortly after writing to the embassy? If so, then what's the rush? You can stay for 60 days, extend for another 30 days and save more money (you have nearly 90 days for now). Then go back to Pakistan or exit to a country where you are entitled to apply.
