American Tourister — Inordinate delay in servicing and misbehavior of counter staff

I have given my american tourister trolly bag for replacing one of its wheels at new horizon at burdwan in west bengal almost 2month ago, till date it is undone by the company and the behaviour of the counter staff is very very rude. He is used to abuse the customer rather than entertaining. My earnest request to the company is to probe against this matter.
