Why are some immigration offices in Thailand asking applicants to return later for Covid-19 visa extensions?

Recent experiences from various immigration offices in Thailand reveal that applicants seeking Covid-19 visa extensions are being turned away and instructed to return at a later date. Specifically, a user reported being told to come back on the 30th after visiting the Pathumthani office to finalize their extension. Comments indicate similar situations at multiple offices, including Phang Nga and Phuket, where applicants are told their visas aren't ready or to return closer to their expiration dates. This pattern suggests inconsistent procedures across different immigration offices regarding the handling of visa extension requests.
