In bkk which is why we phoned first to see if we could go to the much nearer office, said yes then yes when we got there -then no. They should really know what they are talking about but it seems they don't sometimes. Rang the immigration helpline once with a fairly simple querry-25 mins down the line and being passed to four different people nobody knew and we were given another number to ring, which nobody ever answered. I think what pisses people off is the constant changes to the rules and within that the seeming freedom that individual officers and offices have of interpreting them as they wish, confusion all round can be the result.
