On call i got to know that refund amount will be processed in orginal mode of payment for which i was not ready so i asked executive not to take any action keep my payment as an advance and it will get adjust month on month basis and call disconnected. But *n **th Nov in evening i got the message from vodafone that refund request has been initiated immediately i sent an email to cancel this request but executive said refund has been initiated. Merchant Vodafone and Niki took too much time to provide refund in paypal account becuase paypal team is not allowin g me to use that refunded amount as per them the vailidity of the voucher has expired.
