Discoloration, bands, and bumps 6 months post op weekend neck lift. What can be done about them? (Photo)

First I want to preface this by saying that I reached out to my surgeon to get these questions answered and he has not responded to me in over 3 weeks. I am experiencing continued discoloration on my neck I want to know how long that will last and what I can do about it. I am also experiencing ridges (as pictured) on the right side again what are they, what can be done about them and how long will it last. Lastly. I still have a double chin. The base of my chin still sags. Why.
