Botox and filler did not work at all for my frown marks. Suggestions for what to try next?

I have very severe frown marks, there are more like dents in my skin. I had both botox and restalyn on two occasions. Second time did not decrease in the frown indentations on my face after the filler what so ever. Botox was given in the same session. Frown indentations actually became more intense after the filler - as if the filler was pushed by my muscles outside of the indentations? Any suggestions of what to do instead would be greatly appreciated.
