Footnote to the above; I received 3K UKP almost immediately with a promise of TWO more lesser sums. One was posted a day later to my Thai address despite me appointing my daughter as my agent with a Yorkshire address. I had explained by phone that no Thai bank would accept a cheque of this nature AND Thai post is usually unreliable. One month on - no cheque; my complaint is still 'pending' (despite an assurance of a 15 day turn-round) and HMRC still has my money.
