Who can I complain too?

I’m not one to complain ever. I get lots of rudeness being a Latina it’s sad to say but I’m used to it. But anyways today I went to the hospital with my mom, the specialist she is seeing is located inside the hospital so I usually always go with her and I translate for her she knows lots of English but needs help with some words or me explain whatever to the dr, nurses. But today they said the had a translator on the phone it was hospital policy and it’s ok fine ok I told my mom u didn’t even need me here lol

It took so long for them to speak whatever in English then for the lady on phone to ask to repeat and I’m assuming whatever was being sold to translate on computer idk not sure how they do it but it was so time consuming and I was right there I could have done it quicker and plus my mom only needs help with some words. Ok so the dr was so rude he seemed upset we needed a translator over the phone he was yelling at the phone raising his voice to us my mom asked for one word to be translated from me and he flipped out on her and said no she had to use the phone! I couldn’t fever speak they got so confused with the translator my mom was getting frustrated as was I

I couldn’t say anything when I knew the answers

I literally spoke up and he said no I’m the dr not you I’m the one who makes the diagnosis but I was only trying to explain the situation bc they were all confused with the translator. I wanted to walk out so bad. I held my tongue and didn’t say anything. I am grateful for having a phone translator but I didn’t like the drs attitude. I’m not mad at the long process but they way he spoke to us and the lady on phone was ridiculous

So who can I complain to9? is he his own boss ?

Should I let it go?i feel like he didn’t have bedside manners there’s was no need for his actions
