Respected sir,
My name is Shivdayal amrute. I recently ordered a whisper altra clean sanitary pad from Amazon on 14December2020 and then cancelled it on the 19December 2020. Amazon initiated the refund on the same day but the refund has not been reflected in my account. Amazon gave me this Refund Reference Number: 30005403530345181956307and said to complain it to my bank.
