Byju's — service offered of tablet and its content

Hi myself deepak jadhav,
I want to cancel the product of byjus as we are not happy and requesting the team since last 3 weeks but the issue did not resolved. They have debited amount of 6875/- from my account without any confirmation on continuation of services. The representative mr sidhant who had come to our home has promised that the money will be refunded without any question asked but now he is not able to help in this regards and very smartly removing his hands from this mess. We always raised issue about the product long term reliability but very smartly they ignored and said that the mentor will call and resolve but it never resolved to our satisfaction. We feel like that we have been cheated. The byjus are cheating peoples by false promises. I would be happy if all the money debited to be refunded at the earliest.
