Groupon mistake - left with indentations all over my face

Full face fraxel, but I just wanted areas that were missed from the Fraxel Repair I had last year, so I told him to skip the oter edges. Im broke after bad investments & retired disabled so tried the Groupon offer because I just wanted a touch up in the center of my face, that did not get much treatment from the CO2 Fraxel. A Medical Assistant did my Fraxel, but and he kept going over the outer edges when I asked him not to but he said he needed to feather it. Those areas were very smooth as silk and that is why I didnt want him touching it; dont fix it if it isnt broken, but he kept going over it trying to fix the streaks, it but only made it worse. He was using a lot of pressure and it felt like it was ripping at my skin, so I had to tell him a few times to lighten up. I didn't think you could screw up Fraxel Rastore, but his hand pressure was extreme, and the streaks are actual indentations all over my face but especially areas that were smooth. Im not feeling optomistic. They wanted me to return but I asked what full price is. Groupon listst their full price as $350 but the secretary told me $550. It's not worth it at any price and Im regretting it!
