Apollo Hospitals - Wrong surgery done without proper checkups

On **th May I had a snapping problem in my right-hand elbow and I came to the Apollo hospital Bennargatta Banglore and consulted Dr. Mansih Samson. The problem that I was experiencing in my hand, after checking the hand visually without doing any test should have been found that I have a problem with my right hand ULNAR NERVE. A surgery date of **th May was given and the surgery was performed on the same day. They did ULNAR NERVE TRANSPOSITION surgery. After ** days the stitch was removed. Then the next day after the wound started to heal, I started feeling excruciating pain and the previous snapping problem in my hand remained the same. Then it came to the hospital and after seeing the doctor again he advised me to put arm pouch for another week and gave me medicine for swelling and pain and told me to wait for next week. There was no change in the next week, so after wasting the last few weeks, Dr. Manish Samson suggested me to Dr. Naveen Rao. Dr.Naveen Rao confirmed that it was a failed surgery. Today is the **th day After this surgery. Still, the swelling and pain remain the same. After that, I met Pro. A Dr.named Deepa who was there contacted me and promised to help me in whatever way I need and after then now she is telling me she needs more and she can't help. They asked to do a Dynamic MRI during my last visit to the hospital two weeks ago and I did it. And they found that I have Snapping Triceps Syndrome. Then why did they transposition my ulnar nerve? Without doing proper checkups why did they done surgery? Who is responsible for the pains I have endured so far, the money I have spent, my time wasted, and the financial losses? I have not received an update on this
