Complaint against Jabong.com

Dear Sir,
This is regarding one of my order (Ref:150202527019089) from jabong.com for which I requested a return because of size problem and not liking the product.
1. The return collection executive (Nilesh: PH: 9699780075) came to my home without informing me. Since I did not know he is coming I did not leave any instructions for my parents at my home.
2.When he came, my father handed him a wrong item. Instead of s. Oliver black skirt (~1500INR) my father handed him a Vero Moda black skirt (~ 1300 INR, non Jabong product).
3. After 4 hrs of knowing the mistake, I tried calling the executive back, he never answered any of my calls.
4. I lodged complaint to Jabong.com in this matter, and after so many days I receive an answer that they would not be able to trace the product as it is a non-Jabong product.
5. I would say that why so many days were spent to tackle the problem. Also as it was collected as a Jabong product (though in disguise) with a Jabong label, why it is difficult to track that product?
6. I don’t think that its some impossible task to do, when they are handling such large chain of brands.
7. You can understand now I am stuck with one product which I am not satisfied with as well as I am on the verge of loosing another good product of mine.
This was my first ever experience with Jabong. I would say this is a very serious matter of dissatisfaction. I am unable to understand why the executive came to my place when he was not able to reach me. And he should not pick up the product when I was not there. I did not expect this standard from such a large chain of E-commerce brand.

Thanks in anticipation
