I have long history of stay in Thailand on visa exemptions and multiple border runs + extensions last year. I was denied entry last year, so I used the safe entry service.

Are the safe entry service (where they do their preliminary check based upon your history, and help you enter) still operating? How much are they charging these days? If you have reputable service, please share.

With your history of staying in Thailand too often suggest you contact agent direct.

Simple Google search list various agents.

You should start thinking of alternatives.

PM me for a suggestion on an agent.
