Big Bazaar / Futurebazaar / Future Retail / Hometown — unprofessional behaviour

Address: 605001

This is to inform you that one ms. Chandrika working in the checkout counter of big bazaar outlet in providence mall pondicherry is extremely unprofessional and very rude to customers.
On 6.1.2019, at 2 pm, we had asked her to use our discount coupon of 300 rupees on homeware above 1500. She didn’t inform us that towels and mats are not included in that category (Which she too was unaware of) and proceeded to divide our bills into two so we could awail the same. After billing we realised there was no discount given. On enquiring, rather than clarifying the issue, she behaved very rudely and directed us to the customer service. She also threw the shopping bags at my husband who then had to fold and pack everything. The senior person at the consumer service was very kind to explain to us the miscommunication.
I think a person working in such a prestigious chain should know about their products and also their programmes. She cannot take out her ignorance on us through rude behaviour and words. Kindly do the needful
