Thanks BKKROP,
Have used all my Thai PAYG phone credit holding on the Thai contact centre line (ok was only 75 BHT)
Think I will visit the ticket office tomorrow (I am ROP Gold), and will post the outcome.
I am in Ratchaburi at the moment, so only a couple of hours in a minibus.
May well work in Malaysia for a week to let the backlog clear a bit. My Thai wife will be more dissapointed about returning to the uk late than I am !
Regards and Thanks,
Graham
