Dr Batra's — Not giving refund

Hi, I started acne treatment at Dr-Batra Fatimanagar branch on 19/4/2022. They charged me in all 14000/- Rs (13500-for treatment+500 cash for consultation) for 3 months treatment with 6 sessions and doctor checking which she never checked.I paid whole amount. They provided me one powder, few tablets and facewash for just 15 days and I had first treatment session on 2 May, 2022 . After this session my face had more acne than ever before and it got literally worse than before .I didn't take any tablets after this .I had called them when no one responded .Later on I went to clinic to show them what happened and they told me doctor has gone on holiday and won't be available for more than a week. I couldn't wait till that time as my situation was worse so I immediately went to another doctor for treatment. On 21/5/2022, I again visited clinic and told them that I want to stop my acne treatment as I no more want to continue it as their products are not suiting my skin at all and what ever is charges for 15 days just cut those and remaining one's refund it back to me . But another doctor started saying no refund and all .My face was literally with red spots and they are saying they won't give refund and also I wanted to talk to doctor who started my treatment(which she never once checked on me in this time period), she was not there and will be back after a week. I want my refund for remaining months back . Charge the charges for 15 days and give my remaining amount back as soon as possible.
