Address: 208012

Respected sir/ma’am,

I am writing in reference too my cashback that i haven’t received from myntra.

I would like to brief you regarding my matter.

I made a transaction of ₹18, 060 on 30th jan, 2019, from my debit card.

I purchased 14 items, of which i returned 13 items.

Out of the 13 items i haven’t received my cashback for 6 items and the total for the 6 items is ₹11, 317

I followed up with myntra regarding the amount which has not been credited.
In response to that, they have sent me an email, with the reference number of the credit that they have done in my account.

But it’s not showing in my account. I also went to the bank to see my statements. But it’s not showing up.

I really seek your help in regards with this. Why the amount has not been credited to my account.

The bank reference number is-[protected].

My order id is - 110074420011152175701

I am also attaching the mail from myntra they sent me, for your reference.
If you need any other information from my end please let me know.

I will really appreciate a quick response to this email.

Thank you.
