Cars24 Services — EMI is debited on wrong date without any pre information and made it as a house

I bought a car on cars24 app, for a EMI, my EMI date is 6th of every month, for the first three month they detected properly, suddenly on the month of November the EMI was not detect on EMI date that is 6th of November 2021, instead they detected the EMI amount On 9th of November 2021, unfortunately my credit card payment was detected on 8th of November, so the amount I maintained for cars24 emi is used for credit card, and later on 9th of November 2021 cars24 detected my EMI without any pre information, that time there was no sufficient balance on my EMI account. And it was made as a bounce EMI on that month, if they had informed me proper, I would be deposite the money, with out knowledge they did all this things, and fined ruppes 1400 for bouncing charge, i rised the complaint to the customer service my time, but they are not even considering my issues
