Well you could try phoning the local Council tax office and saying something like "I want to check on my council tax payments because I think there might be a mistake, I thought I was down for direct debit .. (or something like that) and then say 'its 24 Acacia Drive, Wapping' or whatever and they might say - and what is the name .. and you say "Suzie .." you might have it in my maiden name, which is Jones" or is it in my married name ... and they might say 'oh we have Simpson' or something .. if it all goes pear shaped just hang up and pretend you got cut off. Or you could say "what name have you got down because I keep getting Council tax bills for Joe Bloggs ... and then they say, oh no we have got Suzie Jones .. is that you ... yes you say .. anyway you get my drift ...
