What are the steps to obtain a certificate of residence in Ubon Ratchathani for a Thai driver's license?

Hi All-I recently went to the Ubon Ratchathani immigration to complete a certificate of residence so I can get a Thai drivers license. I had downloaded the form form the thai immigration website and secured all the required documents. However, when I went to the immigration office they told me they do not issue certificate of residence and that I had to go to the transport office(note there was only one person working and I was the only one in the office). So I went to the transport office and after talking to 4 different departments I was told that they don't issue certificate of residence and that I need to go to the tourist police office to get one. Did not manage to get to the tourist police today, but will try on Monday. However, the websites I have seen clearly seem to indicate that immigration issues these certificates, but with Ubon immigration saying they don't issue them, looking for some advice on what my next steps seem to be before going to the Thai tourist police on Monday.
