Think & Learn / Byju's — Gmat tablet course

Address:	Bangalore, Karnataka, 500081

I ordered a 4 month gmat tablet course for 30k but for some reason had to cancel it. I shot out a mail within 24 hrs to their support team. I called their helpline numbers as well but was always provided with the stock reply: "concerned team is looking into the issue and we shall contact within 24 hrs". Any help? I am expecting a full refund of the amount as the product hasn't even been dispatched. I have contacted them through their online portal as well but to no avail.
