Reliance Digital — I'm complaining about service experience

Hi, my name is Ravindra Ranjan. I am from Patna(Bihar) and my home is in Rajiv Nagar locality. My nearest Reliance Digital store is in Patliputra(Uno Complex). I have bought many products from there, initially service level was very nice but now I think business has grown and they are no more bothered for service anymore. I had selected AC of LG company and wanted to pay through credit card and get the same converted into EMI, as I always do. But swipe machine was not working and it is not working even today. No one bothered to inform me same, I had to personally visit the store to figure it out. I thought of get it financed, but no one came forward to assist, and finally when after waiting for help I was leaving the store, a staff by the name Amit Jha casually asked what happened and after knowing the issue instead of help simply said ok and walked away. This shows they don't care. I don't know how much do customer service means to you, but for Patliputra it means nothing. They don't give damn to customer and customer service. Thought should bring in your notice the issue, may be you care. Thanks
