Poor etiquette and unhelpful

I was having a look at a listing Cherie had, we communicated via email for my enquiry. I asked quite a few questions which were not answered after I asked twice. The one I asked about was if pets were allowed because I have a cat, and she was short off. I then asked about fibre, and the water and electricity and that was not answered because, I was honest in saying that we don't earn triple the rent but we can definitely afford it. Only for her to say 'Sorry, can't help you then' without answering me. There was also no signature on her responses, no hello, nothing. Very unprofessional and she was unhelpful.
