Hypothetical question

Has anyone dealt with something like this? I'm not sure what my options are.

someone copied my website design. I've been dealing with this for about 11 months now and the situation isn't improving.

This involves software/code I developed over the past 9 months. I do have documentation proving my ownership and timeline.

What are the risks if I pursue this? What's the likely timeline?

Illustrative response

I went through almost the exact same thing.

What trips people up most is escalating to a supervisor/manager. I'd recommend following the formal complaint procedure instead.
