[Botox] I got botox for my jaw, but it didn't work.

I got 50 units of jaw botox, but it didn't work.. Rather, for a week after getting it, it felt like I clenched my molars... When I got it before, the effects were immediate and my jaw was weak. When I went to tell them, they just told me to touch it up, so I got an additional 25 units... This time, I didn't get half and half on both sides, but 2/3 on one side. It didn't work for 1-2 weeks after that... The feeling of clenching my jaw continued... So when I went back, they put me in touch with the director. When I asked to see the director who gave me the botox, the director kept repeating that he would give me a chin injection or a fat dissolving injection... In the end, I ended up seeing someone more senior, but they said they would only give me the cost of going back and forth, and that I couldn't get anything more, so I ended up getting it... I don't want to go to places that have events... ㅠㅠ
