Khadim's — rude behaviour of employee in adyar bridge road chennai

I have purchased a sports shoe of smaller size, wanted a bigger sized one so went for exchange but it was not available, in the meanwhile i was looking for other shoes in the showroom. The employee named bihu roy empid-21528, took two different shoes and packed me and gave it, when i asked him he was answering rudely. As the size was not available i purchased a different shoe later with a higher cost. But the employee was very rude with bad words. If you are not taking action against him i would like file a complaint over the show room employee.
