I purchased a product on amazon on 12th august 2021 by using amazon pay later landing partners idfc first bank and then EMI paid through canara bank google pay UPI on 23 august but refund was not received and i asked then for refund. As per their confirmation refund was initiated on 26th august maximum time frame was 5 days. Still it was not reflected in my account. They had provided the refund reference number as 2uQ5y8scnEvUsOD7Xach. I had contacted your customer service number they is no proper response hence i mail you. Please check and confirm the status if your response was worst in mail too i'm going to file in banking ombudsman.
