What should I do if I was refused entry to Thailand due to insufficient funds and how can I resolve my visa issues?

Thank you for the add. I don’t use fb much so please bare with me.

Up until October last year I was on a non B unfortunately due to financial problems I had go back on a tourist visa.

I flew to Laos receiving the 60 days I then extended a further 30 days at immigration.

After this I did the boarder run.

Last week I flew to Cambodia staying 2 days on my return to swampy airport I was refused entry no reason was given.

However in my passport it says insufficient funds I was never asked to produce the money.

What advice could you kind hearted folk give . I did try previously to use the Vientiane booking site but no matter what email I use it says account suspended hence the reason I went to Cambodia.
