Toothsi — Demand for refund

I paid 5K as down payment on 2nd sept 2022 6K is pending but i don't want to pay this, cause toothsi told me my entire treatment cost is 45K but now it becomes 59K... I am demanding my money back, i don't want to get any service from toothsi, my plan is not started yet and I don't want it to start...
But they forcing me to pay remaining 6k for initiate toothsi plan, when i decided I will not proceed, how do they force me ..

At the time of paying the amount I asked their executive whether I will get my money back or not, if in case I decide to cancel toothsi plan... he told me that I will get full refund, he never told me about the deduction also... Many things are hidden from me..
Everytime when I got a call from toothsi, definitely it will be a new person to me .. till now i spoke with more than 12 people... I am also fed up with this calls ...

Now I am getting messages to upload documents to initiate loan process..
I think I have right to decide whether to proceed or not after toothsi paln, so they can't force me to upload documents...

I feel they just trapping the people, they're not going to give us refund, we don't have to right the cancel their so called toothsi plan??
I will never be quite, i can approach to the court... If any customer facing the problem from toothsi as me, can contact on my number [protected]..
I will give the proof of their fake promises and hypocritical character..
