I brought an phone from amazon india (Oneplus 7) and cancelled it when i changed my mind before delivery, the order was prepaid so it was to be credited back to my corporation account the within 2-3 days, the original order was placed on 28th of september and today is 12th october, no amount is reflected in my bank account still. The bank managers and people at the local branch were no help at all too. Please see to it that it is refunded, the refund was processed by amazon
