Wife's foot doctor didn't do what he said he was. Used dead skin to close an amputation. Didn't hold said it was fine. Got infected.can l get help.

Took my wife to hospital in jan. 2017. Had gangrene in between and behind toes. Doctor said he would take off half her foot making sure to get all the infection. He took off just behind her toes and used part of skin he said was gangrene to close it up. It didn't hold he said it was fine it would just take longer to heal. As a result it became infected again this time went into the bones. Had to take her to another hospital because the one used wouldn't take her. This new doctor amputated where the first doctor said he was going to. Now she needs 5 weeks of skilled nursing. I feel like if he had done what he said to start with all this could have been avoided.
