Byjus — False EMI promise and repeated calls from banks

I had enrolled for a course for my son who is in class 7 around 5 months back. I had a video chat with byjus executive in which he told me that my son will get the course for 71000/-. for which i had to pay a registration amount of 5000 which i paid. They even told me that for rest of the amount i can pay installments of 5507/-. all these talks were going on in video chat. he sent me a document in which i had to sign digitally regarding installments . I signed that document. i was informed that if i cancel the course within 15 days of enrollment i will get my refund of registration fees of 5000/-.I signed in a white paper stating that i agree to pay the installments of 5507/- and sent them a picture of that paper in whats app with my other documents. I paid them registration fees of 5000 there digitally. Next month the first installment of 5507/- got deducted from my account. Sir the next month due to corona crisis i was facing difficulty in continuing with the course so i mailed them that i am unable to continue with the course so kindly cancel the course. After few days i got a call from them that my request has been forwarded to the cancellation department but after they got silent. When i called them again they told me that i can't cancel the course as it is against company norms. I was never informed by their executive during video chat regarding this point. Moreover later on i stopped the installments from my bank as byjus was not responding to my mails. But after stopping the installments i got a call from IIFL bank that I was given a loan of 71000/- by bank for which i had signed a document a document. Sir this is totally a fraud from byjus as the executive did not tell me regarding this. He only told me that i can pay the amount in installments but nothing was told to me regarding loan. Now for the last 4 months the IIFL bank officials are continuously calling me at month end and threatning me to deposit the installments on time otherwise they will destroy my CIBIL report. Sir i have sent numerous mails to byjus regarding the cancellation of course but they dont revert. The last mail i received from byjus was on 2 july 2021 stating that they have forwarded my request to concerned department but after that they have not responded. When i call on their customer support number they never give me satisfactory answer. Sir i am very dissatisfied with byjus as they gave me misleading information. I was even not allowed to read all the terms and condition of byjus as i was not shown the complete document online. Sir their customer support service is pathetic as they dont respond. Sir by any means i have to arrange for the money every month even in this corona crisis due to which i am feeling very distressed. SIr i am filing this complaint against byjus so that my problem can be solved
