Politely email your local embassy for clarification indicating intent to fly soon. Hopefully you filled out all details correctly as apparently if info incorrect it might be up to 3 days for consideration by embassy and then lodge a new application.
If it's been 3 days already best to email, greet and thank them in Thai(Sawadee/khapom), I think embassy staff working really hard at present time.
Having written to embassy last night they have decided to process visa today. I submitted one bank statement showing 800 pounds, perhaps they considered this insufficient, have topped it up today per chance they change their minds.
Perhaps they need see 1500-2000 minimum for assurity.
