What are the challenges in extending a retirement visa in Thailand based on personal experiences?

Hi, thought I would briefly post my experience of visa extension, retirement visa. I went with a friend who was applying for their extension. Bank took two days. Then ended up freezing account for 4 months. Has to be done. In case my elderly and frail friend is a Cambodian scammer or operating mule accounts. Then back to immigration. 12 folders. Then told TM 30 and rental contract and payment slips not enough. Even with every other detail and proof.

Go back and get a signed copy of their ID. Several large photographs of my friend in front of and inside their rental house. Large colour print out of the location from google earth.

Ok. Did that, back to immigration. No. Now you need the rental contract to be a year. And when you do that, if we grant retirement visa, you will be visited every month by the police. Given that my friend already owns several condos elsewhere.1200 k away, that seems somewhat harsh. So essentially they have to leave in the middle of their extended holiday. Fly back to their nearest airport, take a taxi some 150k go to an immigration office there and hope they dont come up with another set of rules. Then taxi back, another flight all to extend a retirement visa. They dont like us. They dont want us here. Thailand for Thai's. I should add the banks cheery assertion that document given out by them would be good for 24 hours for bank book and four or five days for statements was met with refusal by immigration. ''Go back and get them today.'' And no I wont name the provincial office. My friend still has to deal with it.
