My online order no.[protected]ladies sneaker) delivered on the 7th of Aug. 2021, at 5.50 pm. to Sushant lok 1, Sector 43. since the size was a bit big, I requested for an exchange but was told by customer [protected]@adidas.com that there was no exchange offer but could be refunded. Pick up was made on the 12th of Aug, 2021 and an acknowledgement of product being received was mailed to me on the same day. It mentions that the product after going through QC, will I be eligible for a refund. A few days back I had sent a mail to customer care and attempts to call even earlier has been met with stoic silence. I am now out of the country and have provided CC an alternate number to reach out. The no. for your info. is [protected]. This is now the 14th day and still no refund or call nor messages. I had in total bought 5 pairs of Adidas ) in this last one month (check your database if you have to, I don't lie) and had no issues.
But this one incident due to the callousness of your customer care is turning out to be a nightmare. Big Brand; so everything should be oh so, professional or so I thought. Anyways, Non the Richer Non the poorer. I hope you understand.
