I had a very strange exchange with her a few months ago - I sent her a Whatsapp with a basic enquiry asking along the lines of whether she was in the city centre and free the next day, for an hour, and I'm always friendly and polite, but I got an instant reply saying she wasn't interested and to 'never contact her again on this or any other number'! Not sure if she thought I was someone else, but it seemed a strange way of doing business! I'd never had any dealings with her before that and nothing since.
