Wa `alaykum As-Salamu wa Rahmatullahi wa Barakatuh

To call Allah for help and support and guidance and to make dua explaining and talking about the hardships a person caused you is acceptable. People are asked first to forgive and relay matters to Allah for what He the Almighty decides is the best. And for that I am not in favour of cursing others in general.

Now, if one is to make a Dua, it must be in a language of asking Allah for support.

O, Lord help me against this unfairness and injustice that fell upon me… like that.

Almighty Allah knows best.
