Myntra - Invalid "Insider" Gift Voucher

** June ****: I claimed **** insider points to get a Myntra gift card shopping voucher worth Rs. ****. I received a confirmation email about the same.
** June ****: I tried to apply the gift voucher along with the pin to my shopping cart. However, I kept receiving an error that the voucher has already been used. The specific error message is: "Gift Card has already been added to user a*y*m*r**@gmail.com."
** June ****: I raised a complaint with the Myntra customer care and the ineffective people monitoring the mailbox simply did not understand the issue and kept giving me irrelevant resolutions. Incident# IN********************.
** June ****: I called up the Myntra customer care team at around *:** pm and spoke to a person named Manish. I spoke to him for about ** minutes and he was the only one who understood and investigated the issue. He assured me that his manager would call me back. He acknowledged was that this is a technical issue from Myntra and explained the issue as follows:
Basically, another person by the name Acy Hmer (or something similar to that) with the contact number ********** from Tripura also enchased his Insider points for a gift voucher worth Rs. **** at around the same time that I enchased my coupons.
The representative confirmed that this is not a fraud case and is a technical issue wherein somehow one gift voucher was generated for two separate customers and he assured me to have this fixed in ** hours. It’s been ** days since I’ve spoken to Manish and ** days since I encashed my Insider points. I am stuck with a Gift Voucher code that I cannot use and the Insider points also haven’t been refunded as yet.
* July ****: When I lodged a complaint on their Facebook page, they kept assuring me that this will be resolved in ** hours but nothing has been done till date.
