What can be done to correct double chin, sagging and lumps caused by Radiesse?

Hi ! I had some very badly done hyperdilute radiesse done on my neck that did not fix any wrinkles but gave me a double-chin, a sagging neck at the top and small lumps. Is there anyway to fix this? Please see pics - prior to treatment there was very little double chin or upper sagging. I was thinking maybe a threadlift?
