Forehead filler side effects..

The place I went to keeps deleting the review I wrote on Naver right away, saying the clean system is operating.. I wrote it honestly without any intent to defame. I searched for and went to a place near Sinnonhyeon Station famous for forehead filler. After consultation with the consultation manager, all procedures and volumes were decided. For my first procedure, I wanted 2-3 cc, but they strongly said I had to do 4 cc. All consultations, including whether I could get a dissolving injection, were done with the manager, and the structure was that I met the doctor in the procedure room. The consultation manager said, “If you dissolve it, you will go back to the forehead you had before getting filler,” but... after dissolving it, I don’t know if the tissue sagged, but it became bumpy -> after consultation, filler was redone -> the left side became sunken and there was a protruding area -> from then on, I had procedures more than 3 times to make it flat, but the bumpiness continued (they said there was no problem with the procedure) -> in the end, they dissolved it while using ultrasound, but I’m stressed because what used to feel hard and bumpy when I had filler is still there exactly as before, whether it is scar tissue from tissue damage during forehead dissection or a granuloma formed.. I went back for consultation, but they recommended a forehead lift (they kept saying it was a muscle problem. But considering my muscles were fine before filler, I wonder if they could really develop like that in just 1 year and 6 months) -> I had a forehead lift consultation at the hospital they recommended, but they said I didn’t need a lift and that the bumpiness would continue after a lift. After the consultation, they told me to contact the filler clinic, so I messaged them on KakaoTalk after that, but they read it and ignored me.
