Amazon — regarding delay of refund of cancelled order

Address:	Solan, Himachal Pradesh, 173212
Website:	Amazon.in

The issue is regarding Order refund, I ordered the product from amazon.in and received on 2nd Oct, but due to its defectiveness, I cancelled it and asked for its refund and amazon told me to cancel the replacement order in case If I need its refund.The product is Marvo Scorpion Black Light KM 400 Gaming Keyboard and Mouse Combo costing about Rs 2199.00 (Black)) having order ID#[protected] between 11-15 Oct but now its been a long time and when I try to check this order no. in order history, there is no such order, I haven't received any refund yet and I have contacted the customer care multiple times and customer representatives just giving the same answer repeatedly again and again that your request is forwarded and will take 24-48 hrs. and once the product reaches to the fulfillment center the refund will be auto initiated to your original payment method and this issue has been forwarded to our investigation team regarding refund, but its been over a month and a half and nothing is resolved, It is my hard earned money, I have suffered a very big harassment and wastage of time for this.

So Please solve this issue at early as possible.
