How can I resolve an issue with my Non O visa labeled for business instead of retirement in Thailand?

Ok so need a bit of advice from those in the know. I arrived in Thailand on a Non O visa on the 18/06 went to the local immigration office yesterday to get proof of where I am living ( to open bank account ) To get all things sorted for retirement extension. Hit a bit of a wall when the immigration officer said you can not ask for the retirement extension because in thai in the remarks line they had written business. The application was submitted via the London Embassy. Has anyone a) been in this situation, and what solutions did you find. The Officer said you need new Non O go to Laos and apply there.

My possible solution and happy to be shot down if this is a stupid thought is go to Laos return on a visa exempt stamp and convert that in country to a Non O and then take the retirement extension.

In a perfect world trying to get the authorities to reissue a copy of the original visa with that word removed.
