What happens when my 30 day extension runs out on April 9th if I can't fly to Europe. Can I keep extending my Visa?

I went to emigration in Jomtein today for 30 day extension. Thinking I had all the necessary documents. I handed them to a guy who was outside the office and was offering assistance filling up the forms for a few hundred thb. Thinking I had everything in order he informed me that I needed written proof of my accomodation. As I didn't know about this he said I could use his address if I gave him a thousand thb. Needless to say I went home again frustrated to return another day.

Thanks for information. I will apply in jomtein about 3 days before my holiday visa expires on 11th of March.
