Apollo Hospital — physiotherapy service

My husband was admitted at apollo gleneagles, kolkata at 7th August, 2019. He had breakage at tibia, ankle and multiple fracture at left collar bone and a deep wound on his left knee. he was operated by Dr, Buddhadeb Chatterjee. He is the great doctor I have ever met. His operation was super successful and he released from hospital at 10th August. Hospital send a person to cut his stitches at 20th August. His name is Mr. Debasish Dhara, He was also very good at his work, and a very good human being. After that Mr. Debasish gave report about my husband's wound to the hospital and hospital called me with discharge summary for farther treatment on 22nd of August. I went to the hospital at the decided date, and doctor made some changes on his medicine and ordered to start Physiotherapy as early as possible. And for that Hospital provide me a number of a Physiotherapist, His name was Dr. Kamal Saha. I called his on that day and he cut my phone and never call back, then I send him message through wahtsapp. then he gave me a number of Mr. Atanu Halder. I called him but he told me he had full of appointments for next two days. As I had Emergency I again texted to Mr. Saha for help. Then again he gave me the number of Mr. M. S. Das. When I called him, his wife took the call and started taking history, then Mr. Das talked to me and again started taking all the medical history. Then he agreed to come the next day. And he came as the decided time with his wife. Just entering our room he casually take a look to the x-ray reports, and started therapy with rush. he was in very hurry, he told us that he had to take the train. Just within 10-12 minutes he finished the therapy, he showed us 4-5 types of exercises and told us to do all of that 20 times each in every 2 hours, took 800\- rupees and left. Next day he again came with his wife, and did the same, showed 2 more exercises and give unbearable pressure just the upper portion of his left knee knowing that my husband has 12 stitches to his lest knee and had two clumps just beneath that knee. when he was giving pressure to the that portion the clamp area was paining. My husband told about that constantly even though he was doing that. And left within 20 minutes. When he told me to do all the exercise for 20 times each, I told him, then why dont you do it for 20 times?? he answered that he done as needed. After his leaving we find that the knee wound area and the clamp are become red, swelling and paining .
then I told it to Mr. Saha about his timing and he answerd that he called his therapist (Mr. MS Das) and he told him that 1st day he stayed for 20 minutes and second day he stayed for 25 minutes and add 2 hours for travelling.
My questions are: 1. Why the therapist did njot do all the exercise properly??
2. Why he did not do give proper time and why he not giving any rest to the patient after one set of exercise??
3. how dare he gave pressure to that knee area??
4. why he took his wife every day?? my husband felt uncomfortable for that.
5. How Mr. Saha told us to add 2 hours for travelling?? are you joking ?? Do we appointed him for travelling? If he has distance issue, disagreed to come, we dont give him pressure to attend my husband. What is it??
I dont think that he was a good therapist as because after his treatment my husband's condition deteriorated rather than improved. he also depraving the image of Apollo.
