What should I do if I pre-booked flights while waiting for my workation visa approval from Hanoi?

Hello friends! So I have applied for a workation visa from Hanoi this Sunday evening, provided everything possible and known to me:

- financial(two accounts back home showing funds more than 500k Bhats for six months)

- professional (cover letter, gst registration certificate, screenshots of business, IT returns etc)

-location documents ( current hotel in Hanoi including the arrival stamps, boarding pass, tickets and also lease in Thailand and flights inwards to cnx)

But I made a mistake of pre-booking flights for coming Sunday i.e. 14th as I wasn't certain of applying for DTV when I planned my Hanoi trip and thought it was just a border run.

Do you have any recommendations to have the process expedited if at all any, as I ideally don't want to lose money on tickets and extending hotel here any further.. though that's my last option. I'm happy to even walk over to the embassy if it helps, though any inputs welcome. Also, anyone who applied from Hanoi recently, what was your turnaround?

Thank you and much grateful for this community 🙏☺️
