Reliance Digital — Cancel product and refund

I had booked a wrong laptop through online website on 29th NOV 2020 using ICICI credit card no cost EMI option, I requested PARAS PRIAM Udaipur store manager to cancel the order, he said that it is canceled by online customer care, I called immediately and request for cancelation and also mailed on same day from cancellation,
From that day I am continuously do follow up with store manager and online customer care, Store manager said that I can't cancel the order it will cancel only through online and online customer executives said it is canceled by store only as order in 'ready to pick' stage. both are just throwing mails to each other but no result.
Till date my order is not cancelled, even the order is still in 'ready to pick' stage, so that refund is not generated,

ICICI credit card deducted the first EMI from my card with INR 124 of IGST, if refund is delayed more than 15 days then ICICI credit card will deduct 3% charge on late EMI cancellation which is approximately equal to INR 1764.
Who will pay these charges (124 IGST and 1764)???
It breaks the trust from reliance digital online platforms.
