Byju Classes — Very unfortunate behaviour of customer contact and point of contact

Dear Sir,
After so many discussions with point of contact(i cannot tell the name), i agreed to take admission for my son for grade 7th.CBSE. We paid the fee after listening to false promises about timing of the classes, batches etc.

Later point of contact told us to contact mentor by giving a number. We spoke to her and agreed for 7pm class on a certain day. To our dismay and astonishments, after that everyone who calls us from Biju will tell some reason or the other and says we(parents) have opted for 0530pm class. And in fact they teach us how to understand something. Almost started teaching us a lunatic. And started twisting the dialogue. This is unfortunate for a world class tuition such as Byju. At lower level, this is happening. Even Senior manager level person who talks over phones feels that parents are almost lunatic and not understanding what they are saying. Infact they supress the dialogue and make us feel that we are wrong. This is not good for such a best world class level tuitions. This is spoling at the lower levels.
Unfortunate, for sure I wont opt next year. I opted for Byju just because my son was in the same sister concern class last year.
Thanks
Parents.
