We had the same situation in December, start again with TM 30, TM87, then to counter 7 in Jomtien for the 90 day Non O.
They wanted proof of address (we had done the TM30) and would not accept the front page copy of my chanote but wanted a copy of the back page as well plus a letter from our condo juristic person stating that we actually lived there.
Also they said my wife could not piggy back on my financials for the first year but would have to apply independently (800,000 in her bank)
They were obliviously making it difficult for us leaving 2 options, open negotiations with them (I take care you) which I had negotiated on previous occasions or use an agent.
As we had spent 2 hours in a crowded space (not good for Covid 19) getting the 2 TM30 approval I decided to use a friendly agent.
For the price of a new scooter everything was sorted in about a month that just left 2 multiple reentry permits to do myself (THB 7200), maybe I'll do Certificates of Residence later.
