What can I do to restore my face after masseter Botox (Dysport) treatment gone wrong? (Photo)

I had dysport in masseters on 31/05, 60units each side. Explained to Dr that I didn’t want to change my face shape but correct the bulge that had formed. I was also grinding my teeth causing headaches. However, he did not listen. Afterwards, my face became paralysed to the point where I could not smile. Then my face became gaunt&started to droop. I’ve had 2ml dermal filler in cheeks to help and smile has started to come back but I am wondering what to do to fix my jawline/sagging cheeks&jowls.
