<human>: In no way am I trying to get karma or anything from this post, I sincerely need help and what's better than asking it on reddit. 

So my dad has a heart problem in which he needed a pacemaker around 2 years ago and he also has a history of stroke in his family. Last week he was at work and started to feel very bad like the same feelings he had before the pacemaker but worse. He felt very dizzy and could barely talk. He called my brother to his job site  and called for an ambulance and got admitted to the hospital for severe vertigo. 

When he got discharged, I asked how was it like being in an ambulance and he said he was treated very badly. They roughly handled him and threw him in the back without securing anything (I don't know if that's how it's supposed to be but that's not the problem). He couldn't talk because he throat felt swollen but he could hear the paramedics joke about him having a long night last night and being very hungover and/or drunk which was definitely not the case! He was afraid something happened with his heart.

My dad tells me not to worry about it and maybe I shouldn't, I'm not trying to start a fight or get someone fired but should I do something? Who should I contact if I should? Is it even worth it? I hope I can even ask this here.

Provide a brief overview of the text.
<bot>: My dad has heart problems, called ambulance when he felt really bad, could barely talk. Paramedics treated him badly thinking he was just a drunk.
