Promised treatment would permanently remove dark marks

Loretta promised Me that her pico laser treatment would permanently remove the dark marks on my face , she told me to wait a few months after the treatment to see results , this was her plan to let 60 days lapse so that I couldn't dispute the charges with my bank for her treatment not working. She tried to upsell me on products for $200 that usually cost $5 otc, the whole point of me giving her close to $1,000 for the laser treatment was for me to be able to stop using over the counter products and clear my skin permanently. That's what we agreed upon and she did not give me the results I paid for.
