Amazon India — mystique bluetooth selfie stick

I had ordered mystique bluetooth selfie stick, isnap x extendable monopod with built-in bluetooth remote shutter for iphone 7/7p/6s/6p/5s, galaxy s5/s6/s7/s8, google, lg, lenovo, vivo, oppo, htc, huawei and more by mystique mall amazon) on 7 october 2017 when i got the order it was broken hence i returned the product and requested to replace the product instead of refund (Because i trusted amazon that they will send good product) but when i got the product for the secnt time it was not working and i was given some used product. Hence i returned the product and asked for the refund. It is along 20 days and i have not received refund till today. I tried calling amazon but no use. I did online chat as well but no use. Just refund my money. I will never shop from amazon. So much irresponsible you guys are. You people don’t understand the value of customer.
