Dear sir/ma'am
I ordered branded combo of 3 slim fit party wear premium cotton shirts, size m, on 31 march 2017. Payment mode cod with total amount of 799 (Including shipping charges) and product delivered on 10 april 2017.

Order id #35500

Tracking no[protected].

But the product size is too small and color is also totally different from what i ordered and the quality of product is also very bad.
As per their policies i am eligible for return within 7 days after delivery. But i am unable to return the product and i have sent them mails regarding my issue but no response from their side. Please help me regarding this.
