I often experience people changing the text and then claiming they never posted anything like. It is my hobby to catch people lying, that's why I always do a screenshot before I comment. I am the admin of a very well known and reputed visa advice group and this is just my way to do it (Frank Sinatra) . Michael Moore and ME have already caught the POS in the White House having uttered over 90,000 lies
"I might even use that agency to do the leg work upon the renewal of my 1 year extension stay in Thai. It would not be THAT expensive." . . . . . . . yes, the agent fee for an application for the next 1-year Extension of the Stay Permit should be around 12-14,000 THB, when using your own funds.

“I enterend Thai on it 29. October 2025. on Non-O visa 1 year from an agency that charged me 34,000 THB”

Embassies worldwide have discontinued issuing 1-year Non-Imm-O Retirement Visa by October 2023, and by January 2024, the Savannakhet Consulate was the last one to stop issuing it.
Since then, every Non-Imm-O Visa is only good for 90 days.
It is IMPOSSIBLE any agent got a “1-year Non-O Visa” for you
some of what you wrote doesn’t make much sense, and you seemingly haven’t understood the difference between a visa and a stay permit
you don't need to be a resident in the country, to apply for the 90-days Non-Imm-O Retirement Visa. You can be in any country as a tourist and apply through the E-visa online system of the Thai embassy in this country. . . . . residency is only needed for applications to a Non-Imm-O/A Visa and for a multi entry Tourist Visa
and 10 days left to apply for the extension is enough time. Have you asked Immigration for the list of requirements, yet? So you can prepare everything before you visit the bank for their "bank letter of guarantee" confirming the 2 months seasoning, and the subsequent visit on Immigration
that won't get him anywhere as he can't use his income for the financial proof, and he can't get a Thai bank account opened on a tourist visa (except with some agent's help for a lot of money)
