Good evening... I have this stamp does anyone know if I can get it extended on the visa amnesty? Really confused .. thanks in advance

has anyone who hasn't used their tourist visa extension before the amnesty got their Tourist visa Extension approved (without embassy's letter)?

Any information gratefully received. Hi I entered Thailand on the 01st January 2020 on a Single entry Non Imm O Visa marriage visa with children. So I get my original 90 days on arrival that was due to expire . I then did a 30 day extension at Udon Thani Immigration office then all this visa amnesty kicked in and have been in Udon ever since. I am due back to work in the UK on the 12th October and the amnesty expires on the 26th September is there any way I can extend my stay until my return to work date say 10th October or will I have to depart on the 26th Sept like everyone else. Its not a problem retuning to work as I have to it will be getting back to see my family in the future. Thanks in advance
