Myntra.com — fraud on my account: order delivery address is changed after order is placed, seems to be fraud from myntra employee

Address: Pune, Maharashtra, 411057

I have placed multiple orders on 22nd of december 2019. For 2 of the products the delivery address is changed from pune address to rajasthan address. The products are delivered to rajasthan. Also, there are 2 more products ordered from my account on 2nd of january 2020 using the myntra credit. Both are products are in shipped state. The details of the orders are mentioned below:

Orders for which delivery address is changed few days after the order is placed:
Order #[protected]-3677901
Order #[protected]-1693501

Orders which are placed in my account on 1st of jan 2020 and currently in shipped state (As of 4th of jan)
Order #[protected]-8564201
Order #[protected]-3362003

I have called myntra customer care to raise a request so that the matter can be tracked to closure. However, the myntra customer care person was talking to un-professional. I never imagined that brand like myntra can have this kind of customer support. I had been truly exceptional experience shopping with some of the international ecom providers.
The way the order address were changed and my account is been used during myntra xmas discount, it seems to be a myntra's insider employee role in the fraud. I request myntra to investigate the matter and nab the culprits asap. Now it seems insecure to maintain an account with the site or use a credit card for transaction.
