We found out that if we go to the main NT TOT office in Sakon Nakhon, they will issue the bills in English. So we did that yesterday. Might not make it for the November bill, but should be OK for December. I wrote out the address and my name long hand so that they don't mis-spell my name.
Should be easier to use than a Thai yellow or blue family book, since Falang firms can be quite rigid in what they accept and as I will get this bill every month I avoid the potential, arbitrary "must be no older than... days" rule.
It also turns out that for this specific account application, my bank statement was sufficient. It is just that I uploaded an alias file instead of the file as a PDF which they could not open. So instead of telling me "corrupted file", I got "missing document". Instead of "you need to upload yadda yadda..." (a request) I got "did you know you could upload..." (sounds like FYI). Now that my faith in their processes is in doubt, I am calling their support every couple of days to check if there are any blocks, what is the nature of the block and what can be done to surmount it. At least I avoided the hassle and cost of finding a lawyer to notarise a translation. For now...
