Who will help me remedy the situation I'm having related to housing discrimination ?

I (Black), and my wife (Mixed race) (Black & Caucasian), were served today (4-19-19) with a 10 day notice to cure lease defaults from our landlords attorney. It contains vague allegations, none of which are true. As a standard 10 day notice states, the intention of the landlord is to evict. We have encountered this same type of discrimination before, but unfortunately, we sought the assistance of government agencies rather than immediately consulting an attorney, which in turn led to the downfall of our case against a former landlord and we do not intend to make the same mistake again, now that this type of situation has occurred once again.
