Filler injected into glabella area (Photo)

I’m 41 never had fillers only photos few times in glabella area.Last year I had Botox but two weeks later I came back for top up as first dose did not relax muscles fully.Doctor offered filler.Advised no side effects.no document signed.I was left with two raised lines and now where filler was I have many more lines created by filler as muscle kept moving.He denies it’s caused my filler but I never had those lines before and my glabella area looks terrible.
