Think & Learn / Byju's — less of education and more of harassment

I order byjus and got poor feedback from my known contact. I cancelled the order within 24 hours. The byjus' accept the cancellation and send a mail that money will be refunded in 7 days. Today 14 days have passed, the loan is getting approved even though. I told the person that i cancelled the order but they keep on calling and processing next steps.

Today i received a phone to take delivery of tablet.

Byjus ticket number 372702
