Terrible decision - not satisfied with the result at all

had tummy tuck and lipo on April 15th this year by Dr.Shafran . Cost me $15,500. I paid $5,500 upfront and $10,000 in credit by. Still have a balance of around $7000 that I have to pay. The incision is not straight. My stomach fold up. I have accessible skin and dog ears.lipo is not even in my back. I told the doctor I’m not satisfied with the result at all and I don’t want to pay for the rest of the money in my balance. He said that it’s my fault. I didn’t exercise . Doctor offered to redo it. But I have to pay for the the hospital and the doctor who put me to sleep. Meaning that I have to pay more money, go through full anesthesia , go through pain again and take time off from work to fix the result that the doctor cause. .. I am so in regret that I did the surgery with Dr. Shafran. I have family members and friends who did them and the result as was stunning. They had more fat, skin and more weight
