If I could give 0 stars I would. Man turned up uninvited. Said I wasn't interested. He said 'I can only visit 6 addresses in this area' as if this was my problem. I answered 'So?'. He said, quite aggressively in my opinion 'I'll have to come back then'. I told him I was not interested at which he huffed rolled his eyes and walked away. As a woman on my own I would not have felt safe to let this person in my house. I will never do a questionnaire for Ipsos Mori.
