Need advice: homophobic tutors

I am Pakistani + an Urdu speaker and my partner has been wanting to learn the language via preply. However, people have been cancelling and blocking once he reveals that he’s learning for his fiancé (and mentions my name). I think this is super inappropriate and wondering if there’s a way to report, etc.? If anything I’d like it to be known that these tutors (specific ones) are this way.
