Reliance Jio Infocomm — Refund Not received for Jio Fiber

I have paid Rs 2824 online to the Jio sales executive to get Jio fiber. But due to some bad behaviour of the Jio sales guy, I called customer care I cancelled the order and received one sms on 26 that your order is cancelled and refund will be processed in 10 business days. But still now after 10 business days I havent received any refund in my bank account. My order id is NO0000LNFM9N
