I am writing this get the attention of concern authority of cancellation team to complain about the thoughtless behaviour of the support team, and acknowledgement request for the cancellation of my subscription. I have been trying to reach my mentor for cancellation process but the support team is not helping me, and keep telling that he is busy. My Mentor was suppose to help me in every aspect, but he is busy for last one week for helping me.
I am a subscriber of Aakash BYJU'S Grade 11 12 NEET course and wish to discontinue the service before the end of my 15 days trail period. I have mentioned the reasons below
1: Your executive has told that I will be able complete my board syllabus along with neet preparation which is absolutely a false statements.
2: The concept are difficult to understand in the online classes or recorded video.
3: I don't like the teaching techniques and speed and had complain about it so many time but no improvement is seen.
4: My family financial status is also a reason for my decision. As it is very expensive and overpriced for me.
So, I would like to cancel the subscription provided BYJU'S. I am hereby requesting for the full refund of 15000 which I had paid to access the service

Therefore, I request for guidance of cancellation of my subscription and the procedure to return the Tab. Please send me an mail for acknowledgement for the cancellation of my subscription. If I don't receive any acknowledgement of my request mentioned above, then I am forced by you to complain against the harrassing behaviour of BYJU'S team to the higher authority or police. For any query you can contact me in my registered mobile number.
