Still Have Grid Marks 7 Months After TotalFX

I had Total FX done 7 months ago and still have grid marks, is that normal? The scars are actually getting worse. My doctor says they will improve but I'm beginning to not trust him. He says if they don't he might try more laser. I didn't have any scars before the laser treatment and they are impossible to cover with makeup. What should I do?
