[Resolved]  Flipkart — Security breach by using may old phone number and my flipkart account

My old phone number is being used by some other person "Raju" whom i don't know and never ever shared my mobile number as well. Flipkart customer care is unable to reach and this person is using my account for almost quite long time now. Tried all the possible way but still that number is there with other person and i am keep on getting the notifications in email for some random orders.

My Name: Prakash John
Old Number: +91 [protected]

Please resolve it.
