I’m in NZ as well. I responded to the email from Kate explaining that I wasn’t interested and unsubscribed. The next day I got another one. This time I phoned them as there was a local number on the email. Went through to a pleasant sounding person in the UK. She said that Kate was one of their Marketing people, but she wasn’t available... ;)

I asked her to remove me and she assured me it was done. 
For good measure I unsubscribed a second time. 
Let’s see what happens tomorrow morning!
