I had the same thing, immigration officer specifically told me that it would start immediately and not on the 27th. Did my 60days today, stamped until 15Nov
hey Ben, should I have asked them to changed the dates? They only do that on request? I thought it was standard due to it being officially announced that way.
Addition to this post; at Samui immigration the 60 days start immediately after the extension is obtained. Did mine today. They notified me in advance about it before I paid the extension fee.
