What should I do if my employer refuses to cancel my work permit on the last day of my job in Thailand?

Hi guys. This is my situation. I've worked as a teacher here for many years and never really had any issues here before about cancelling visas when leaving a job. Anyhow my last working day is the 30 th January. I have a letter stating that. Signed and stamped by the school. However my boss refuses to cancel the WP on the 30 th. She says she will do it on the 3 rd.

I spent 4 hours at the labour department yesterday trying to sort this out. The labour department agreed that I was in the right and several officials called my boss telling her that she was wrong and had to comply with thai laws and do it on the 30 th. Unfortunately my boss was rude to staff and before anyone asks no I've done nothing to warrant this.

Her reaction to me wanting not wanting to renew my contract was to serve me notice papers within 30 working days the very same day. I currently live and work in Nakhon Pathom province. Unlike Bangkok the visa can't be cancelled in advance and this immigration give no 7 days rejection application stamp. I have asked them several times and staff at the labour department also asked them for me. I don't know why but they don't do it.

The labour department told me just to walk in school in the 30 th and then leave the country the same day. Then go cancel everything on the 3 rd of February. Then I wouldn't be detained for overstay as I'll have a new 60 day stamp. I will be fined though right? For everyday my visa is not cancelled ? I have a new teaching position in Bangkok and that's why I need the visa stamped cancelled along with the WP. I know once I leave it will automatically cancel.

I'm still waiting for answers at the labour department but any advice from the forum would be highly appreciated. They won't let me do it myself as they said I can't because it's done online. My boss told them she expects me to work to 6 o clock that day . I work for a language school so we work in the evenings. Immigration told the labour department I'm not expected to work the whole entire day as I have the right to cancel the WP and visa and leave the country. The labour department requested ages change the letter stating the last day as the 3 rd but she will not.

It's obviously a stressful situation to be in. My contract was up on the 15 th February and I had every intention of completing it. Any advice would be highly appreciated.
