Car Accident Compensation and Medical negligence

Hi, I met with an accident on 13th Feb 2017 while Crossing road at around 1 am. An overspending overtaking car hit me while Crossing road. After that driver took me to nearby hospital. I got stitches on my chin, minor wounds and my right foot was swollen. Hospital guys gave me first aid & told me that nothing major damage is there. I was still not satisfied coz my right foot was twisted badly. Doctor told me that there is nothing major in x ray I just have to use ice packs and foot will come back in shape once swelling is gone. They informed police regarding the same and did MLC. By that time I was feeling OK and I didn't filed any complaint against that guy coz he helped me after accident & he also promised me that he'll bear all medical costs. Hospital discharged me saying that nothing major and also referred me to visit orthopedic doctor. Next morning I was feeling huge pain in my foot so I called that guy whose car hit me and told him to take me to some orthopedic doctor. He gave me one address of nearby doctor and met me there. That doctor asked all details did xray and told me that my ankle is fractured. He put plaster for 15 days and told me to visit after few days. For that day doctor fees was paid by that guy only. Few days later I got a call from him saying that he needs my help for his car damage claims. I helped him in getting his claims over the call. After that he never turned back to me to atleast say thanks, that guy who hit me with his car never called me to ask about my condition & never met me again. Meanwhile I was regularly visiting that doctor who put plaster on my foot & after 1st day of accident, I bear all cost of my treatment. I was not satisfied with the fact that my foot was not into right position even after plaster, that doctor told me that it'll be OK once plaster is removed. After 15 days doctor told me to continue with plaster for one more week. On 6th March doctor removed plaster and said that there might be some complications and because of the same my foot is not in right position & referred me to get CT scan done. Next day i.e. on 7th March I went to that doctor with my CT scan report. He checked and told me that there is no need of surgery, he'll discuss details with his colleagues and inform me about further proceedings in a day or two. My family members was not satisfied with that doctors observations so they told me to visit some other orthopedic doctor for assistance. Same day I met another doctor and I was shocked knowing that previous doctor has not done proper check & he missed that my foot is dislocated and surgery is required to get the same corrected. I called and informed that guy who hit me with his car about the same, he disconnected call saying he'll call me later. Now I have been trying calling and he is not answering my calls. Kindly help me as I am not getting any help from the driver and also suggest me what to do with the doctor who wasted my 25 days just because of his negligence. Regards,
