At what point can a Mohs Forehead scar be revised and Botox restarted? 4 months post op. (photos)

Mohs Surgery BCC on forehead end of January. Told surgeon would provide scar help if needed. 4 months post op, waited 6 weeks for appt today... told looks good by assistant, and they only address scar after a year. Said they could hardly see scar, and doctor would not be seeing me today. Told In January I could resume Botox, So I went to their office for Botox 6 weeks ago, and it did not work. Don’t know if my forehead will ever be smooth again, no revision/ help offered, and Botox didn’t work.
