Bad agent service

We were looking forward to seeing a perfect property that was really close to us and we reached out to the rental agent to ask if we can arrange a viewing and she had something planned for the Friday which was understandable and said she will be able to arrange something for the Monday at around 12:45. When messaging her at 12 that day, she said she doesn't have the keys yet and then said we can do it the next day. I explained that I need to go to the bank but should be available from 10-12. I kept on communicating with her that the bank is taking long and that I won't be able to make 10am and when calling her at 10:45, she very impatiently told me she cannot just keep time slots open like this.

When ever I spoke to the lady, she was impatient with me and didn't delivery on her promises at all.

I feel that this is really bad customer service and from my understanding, Rawson has the same trend with agents like these.
