Levi's India — levi's denim purchased from outlet in goldighi mall, silchar

Cachar, Assam, 788003

We purchased a denim on 6th jan 2018 from levi's outlet in goldighi mall silchar. For alterations we specifically told we want the denim just folded from bottom. Only after they assured they would alter in the manner we told, we agreed to pay. Despite of this we got the denim 1 inch shorter than told.
This is really annoying and not expected from levi's brand.
Sales representatives someshwar and archana have cheated us. And now what should we do with a denim which is an inch shorter.
