Looking for advice on a legal issue. Here's what happened.

domestic partnership property rights. I've been dealing with this for about 10 months now and the situation isn't improving.

Illustrative response

Crossposting my experience here because I think it's relevant: I successfully disputed a charge through my credit card issuer under the Fair Credit Billing Act. The key was filing within 60 days of the statement date and putting the dispute in writing. The credit card company investigated and issued a permanent credit.
