If it was me , I would just refuse paying.  We could go back to the police station and I would tell them , where are the signs ?   Show me.  
And then if they still wanted 2000 baht I would tell them this would be all over social media and that's not good for the image of Pattaya.

Then I would buy them a bottle of whiskey and wai goodbye.

Hopefully not a 2000 baht single malt... but hey, they got what they were after.

And then they say, "Ok.  Then we charge you under computer crimes act also." 

 

Then you say, "But I will do it outside Thailand." 

 

Then they say, "We leave warrant at airport.  You come back Thailand, you go jail." 

 

Then you say, "Where is the nearest ATM?"
