Should I Pay for Breast Augmentation Redo?

I had breast augmentation approximately 3 months ago to correct asymmetry. The breast are still noticeably different in size by more than 30 CCs. 300 cc implants were used. The doctor used 300 cc on large breast and 380 cc max on small breast. I don't understand why he used the same size implant after telling me that the difference could possibly be up to 100 ccs. He gave me a quote to redo of $2,600 and then changed it to $3,200. I don't understand why I should have to pay for it. He did not fix the problem. I am very unhappy because I paid total of $5,010 and pretty much threw my money in the garbage. I also asked other surgeons for a quote and they said that the doctor who worked on me should redo it for free, and that surgery should have warranty. Should I pay for the redo or insist that he do it for free?
