As we purchased byju learning programme for class 10th to class 12th from the counseller (Atul dubey) on 25 august 2019. I met with my order after 15 days on 10 september 2019. After few days we called the team for support but there was no proper response. After this type of situation i am not interested with your product. I tried to tell my counseller for cancellation but i am having no response from him. After this i want to completely return your product as it is in the trial period of 15 days. So please complete the process of returning the course.
Also return my advance of inr 9000 and cancel nach mendate on my account as soon as possible.
