Byju's — no response to refund request after a week.

Address:

Raebareli, Uttar Pradesh, 229001

I ordered byjus' tablet around 17th september, 2019 and received it on 1st of october, 2019.
After having a experience, i filled a return request for the tablet on october 6th. Their first reply was quick. After that, they asked for the informations. After i provided that, i got a reply soon. But after that, they ignored my back to back 3 mails. Their salesperson or so called 'mentor' also was try to change my decision by constantly telling about their faculty. When i refused and asked to tell ne the exact process for their product's return, he started to ignore my message and phone calls.
I then contacted their priority service. Got a reply at first, but no reply from them too over a week and i've already received message that money will be deducted at the time of emi payment from my account.
Please, i want my refund.
