1 month back a byju's representative came to my house and offered iit+11+12th grade coaching for a sum if 54000. After using it for around 10 days i came to know their coaching is not upto mark and not worth the money. I was unsatisfied and i contacted their customer service after 20days and told them to take back their tab. They refused it and told me that i had only 15 days trial to check the tab but no one even the byjus representative who came to my home or the the customer service informed me about this. Now iam forced to pay an emi of 4500 per month for their unsatisfied coaching. I want to take the entrance coaching at my preferred institute near me and i don't have money to pay both for the byjus and institute. So please kindly take action and take your tab back.
