Dr Batra's — Treatment and the Center

This is regarding Dr. Bhatras Treatment my family is undergoing in RT Nagar.
I started with my daughter for one year for hair-fall problems, all was fine till they asked me to buy an extension of the treatment.
In the last six months or so there was a change of four doctors which didn't allow us to adjust to medicine or doctors and the hair fall problems increased with each visit.
The marketing team convinced us to start a treatment program even for my son, which I did.

Today( 20/11/2022) I booked a courier service to pick up the medicines from the Clinic and deliver it to my place. They delivered another patient's medicines instead of my son's, but that's not the worst part about it, they refused to pay the money for the courier to get the medicines for the second time! I had to pay 120 rupees just to get the medicines and wasted my entire evening coordinating with the courier guys

I want a refund for my daughter's medicines.
For my son, I want to shift my center from RT Nagar to any other place preferably Jayanagar
