Planetspark — No action on cancellation of EMI & refund of my advance amount

We had given 2 months of advance payment during the time of registration. There was confirmation from one of the PlanetSpark's executives who was guiding us through the registration process that there shall not be any difficulty or any hidden agendas during the cancellation of the subscription at any point of time without asking any question. There was also confirmatory mail after the registration process was completed where they had it mentioned anything about then cancellation charges. Now, while i wanted to cancel my subscription there has been so far innumerable mails, tickets raised against my complaints but there has been no resolution and the planetspark is asking for cancellation fee from our side. They are also accusing us that it was our duty to read all the details related to cancellation charges which they had not informed us during admission time or while sharing the brochures. They are neither arriving at any resolution nor they are responding properly to any of our concerns, calls, mails and worries. The management team is saying that stopping of auto debit from my account shall not be happening untill the cancellation of the subscription is done which they are not doing/resolving. The complaints have been raised since 06.02.2023. They had said on Friday (10.02.23) that on Monday (13.02.2023) they would arrive at the final conclusion but nothing is happening till now (students portal chat not responsive, mails not responsive, customer care contact not reachable). They should be refunding us our advance payment, but they are asking us cancellation fee and they are hoodwinking us by saying that their team would soon contact us.
