Byju's — Not working as was promised

I had purchased 4 year Byju's program 2 months back being told that it'll work in Canada also. The sales agent was Mr. Akhand Singh.

But even after 2months the classes link is not working and I was told a month ago that they would refund my money.

Its been a month and I have still not received my money. I am mailing their support team every 3rd day but I just get the automated reply. No one is contacting me personally.

Can you please help me get my refund.
