Reliance Mart — Very very bad experience at Vikaspuri store

Today I visited their Vikaspuri store for daily need shopping and tried to purchase a curd packet too but due to incorrect tagging it couldn't be billed and to my shock when I approached the concerned section to get it corrected a male and a female employee their refused to support bluntly saying they are busy and can't do the same and adviced me to leave the curd and when I reported the matter to floor manager she also replied in same cold and rude manner that it will take time as they all are busy and if I can wait for more than an hour for the same they have no value and respect for the poor customer they are too busy in doing nothing but denying and insulting the customer what is the point of being busy if you can't serve your customer reliance staff is highly incapable and rude highly disappointed there is no point going there anymore for me to shop and get insulted instead
