Byju's — Mental harassment

Sales order No:[protected]
I requested for reschedule of classes on jun 30 as student school has been resumed and it clashes with byjus classes timing, I 'm calling them on daily basis to change the timing as student is losing his classes. It's been 12 days I've requested for it and student has lost 26 classes, but no one is responding and classes is still not resolved. I get promised on each day that they will check and get back to me but none of them came back.
Byju's is doing mental harrassment of customers, I was thinking about the suicide because they are ruining my brother future. To process any request I need to call more than 50 email and more than 50 calls. they always do promise to call back and resolve the issue but I never received any call back and to resolve any issue it take more than two months.
I've sen more than 20 emails to the CEO of byjus but he never replied. Please process the request this time otherwise I'll do suicide on the name of byjus as I'm being mental harrased by byjus and his ceo and their employees.
