I've ordered from two t-shirts from myntra (Vector e-commerce private limited, gurgaon 122413 haryana )
Via order no.[protected] on monday march 14 2016 through india post tracking no. An[protected]in.
Details;
1) ucfbtsht[protected] united colors of benetton white polo t-shirts (15a3dtpj30) and
2) ucfbtsht[protected] united colors of benetton navy & mustard yellow striped polo t-shirts (15a3ap1j60)

But on receiving from post office, the seal was tampered and it was found that only one shirt was missing [ ucfbtsht[protected] united colors of benetton white polo t-shirts (15a3dtpj30) ].

How is the other t-shirt been lost ???

Hoping for positive response from myntra.
