Firstly there is no 180 day rule, that is up to the IO, secondly, the OP doesn'y apply for a visa but uses visa exempt entries and thirdly, staying 6 months a year in Thailand with 2 entries is not seen as typical tourist behaviour
The remarks says "contact business" so it looks like you applied for the wrong Non-O in which case you have to leave before/when it expires and apply again from the start
