Later I realized that they had entered a completely different date of birth, so today I visited the office to ask them to change it. I was a little puzzled how they could get it wrong, after all I did give them a copy of my passport, old license and work permit with the correct D.O.B. However the lady at the office said it wasn't her fault but instead a fault of the main Bangkok office, apparently they had the wrong data on their computer. She insisted that I apply for a new one and pay the fee again.
It's not a great deal of money but not really fair IMO. Surely it's their mistake and they should waive the fee on a replacement. Oh well T.I.T.




, your bad!".
