DIBYA Publications — Din information kit

Address:

Khordha, Odisha, 751002

Dibya publication — sent fraud din information kits for rs.950/-, even though i didn't order it.

I have got a post from dibya publications on saturday (3/ june/2017) saying that it was a din (Director identification number) information kit costing rs.950/-. I didn't order it and i don't know about this company. I don't know how they got hold of my din details and my address. Please make sure that this company doesn't continue this kind of fraudulent activity. Can someone tell me how can i get refund for this fraud?
