If you can't negotiate the inconsistencies and the odd frustration of an immigration office you really have no chance living here long term. First time I tried to get an extension I was told the office did not really do them and to get one in Bkk, though I lived in Samut Prakan and was at the right place, the officer hated foreigners, as I found out on here. Persistence and patience is what you need, not wasting 8k on having your hand held.
