Myntra.com — lucky draw winner fraud

Address:	Gurgaon, Haryana
Website:	www.myntra.com

I can purely understand that i am late in putting up the fraud that happened with me. But i wanted to be sure about the same and have collected all evidences in favor of the cheating that has happened with me through myntra gurgaon.
I am a loyal myntra customer since long and have liked the brand since many years and regular orders to myntra is used to for me.

13th october 2017- i got a call from an unknown number (Wasn't a spam as per truecaller) number was [protected]. The lady on phone shared with me that they are from myntra sales office gurgaon and that i have won the lucky draw prize from myntra for my last purchase.
As any customer will do, i verified the details of my last order. They shared detailed information of order number, product code, mode of payment and even the delivery address. This make me realize that the call might be genuine.
Then i enquired about the gift, and they told me gift will be either iphone 7 plus (128gb), 50, 000 cash prize, or samsung galaxy s8.
Upon subsequent process, they asked me to shop for 3800 inr from myntra and shared they will be helping me in processing order without any taxes since this is only for registering gift item.
I resisted at first saying that i would need a mail from myntra or a message atleast declaring me as a lucky draw winner. Then i can happily proceed for payment.
They then told me that it has to happen now and soon after payment, i will recieve message and a call from accounts department with the details of prize money.

These guys are so professional that they even know the product code for all items listed in myntra. I shared with them 3 items for 4000 inr in total and they agreed for processing the same.

They knew the delivery address as well. They ensured me every now and then that it is a genuine call and soon i will receive text message.
They asked me to share card details so as to process payment through ivr.
I shared otp with them and payment of[protected] first transaction + 1800 second transaction).

For 2 hours i continuosly called the number but in vain. Then i received a call from another number ([protected]) truecaller named it as myntra. This boosted my confidence that it was genuine call.
This executive said he is from myntra gurgaon accounts department and confirmed to me that i have won 50000 inr cash prize which will be credited to my account. He then shared the details as how the money will be credited. Clever cheat shared i will receive money in series of 5000, 5000, 5000, 5000, 10000, 10000, 10000.
He asked me to text him the account details with ifsc code. I shared the details and waited for transaction and order confirmation.

I also wrote to myntra the same day but received a reply that mail-id is not meant for inboxing.

Ever since then i am trying to call both these numbers but it is no more active now.

I have all the call recordings, snapshot of transaction, and mail i wrote to myntra the same day as my case supportings.
Please let me know how to upload call recordings so that i can proof my case.

I felt cheated with such a big brand myntra.
