Design your Interior space with high-quality renders

I instructed Hanisa to design a layout for our garden office, with a rendered visual. I suppled something we had done ourselves, but rather than think and consider the layout as we were excepting, she copied our design exactly and just created a render. Also, missed from the render were two windows, which I'd supplied images of. She apologised, said she would re-design and include the new windows, but since then (over a week ago) I've not heard anything. This was a time-sensitive project, which was all explained in the brief, and now we are having to look elsewhere to have it done again. I have also paid her as she requested her invoice the moment the first visuals were supplied. In hindsight, perhaps I should have not showed her our design, but it was quite clear that we were instructing her to design the layout for us. 2* rating, as the quality of the renders she's put together are fantastic, albeit they are wrong.
