Toothsi — Aligners treatment

I approached toothsi for my forwarded teeth and crowded teeth and for the same I book their consultation for Rs 499 that was video consultation and in video consultation doctor told me about treatment plan and asked me to pay 11000 as a down payment for treatment process till now I had not gone to any clinic nor any impressions I had given next day when I received bad feedback from my friends so I asked them to cancel my treatment as no procedure was done and no impression was done so I asked them to refund my rs 11000 and in mail also I asked them but when I receive the call they denied me only video consultation was done and for that I paid them 499rs but 11000 rs was for my treatment which I have denied next day and now they are not paying my amount no alinger kit I have received and no treatment I have started still also they are denying by saying their company policy for which they don’t told me earlier
