Byju's — They won't cancel my services and keep taking my money

They never told me that they will be deducting the money from my account automatically and I was also not informed of their policy about the cancellation beforehand. When my classes started, in the first month they had good teachers and after the trial period was over their service became completely pathetic. I told them that they can take the money for the services they have provided, but I do not want to continue with them anymore. Now they are spewing their policy terms at me and telling me that they will take money from me even if I am not going to use their services at all. I cannot afford to throw away money like this, and they are not entertaining anything I say, the support individual was blatantly rude, she was not listening to anything I had to say, she was only telling me how I have to keep paying for things I am not going to use. I am trapped and I need help.
