Denied 30 days extension / Tourist visa

Yesterday me and my girlfriend for the past 12 years went to Chock Chai (Korat) immigration to extend my tourist visa with 30 days. I deliver my application, passport, passportcopys and a picture. This was not enough for the lady behind the counter. She asks for a copy of my girlfriends ID. We gave her a copy. Then she asked for a prof of my adress in Surin. I could not give her that because there is not written in the visa-rules that you need a prof of your permanent adress to extend your tourist visa. I ended up with a extension of only 7 days. I wonder if anybody has experienced the same as I did. I browsed the Immigration website last night and found nothing about their "permanent adress prof"

So, what happened? Are yo still in Thailand??

Yes I am still in Thailand. I had to go earlier than planned to Laos to get a new visa.
