Filler hasn't settled or softened in 2 months. What's going on?

I had filler in my chin/jaw area and after 2 months it is still firm and lumpy. I usually use Juvederm, which I have had no problems with in the past. However, this time my injector used a Teoxane brand and it just won't soften. Will this come right eventually? My injector says we need to wait for it to settle before we can judge the final result, as it currently looks uneven.
