Hypothetical question

EDIT: added more context below. Has anyone dealt with something like this? I'm not sure what my options are lol.

SaaS provider changed terms unilaterally. I've been dealing with this for about 5 weeks now and the situation isn't improving.

The contract was signed 22 months ago. I am not sure I have the original signed copy. The total amount in dispute is approximately $134,000.

Do I have a strong case? What should my next steps be?

Ok so nAL, but from what I've read, you should file a complaint. But yeah, have someone look at your specific situation....
