Reliance Mart — failed transaction amount is still not reversed

Address:

Mumbai City, Maharashtra, 400086

3 days back i purchased from reliance mart phoenix market city kurla. I did transaction via card and first time transaction got failed then he told will get reversed den told to transaction again. But the failed transaction amount of 325 rs still not got reversed in my account. Please take action against them as soon as possible. The reliance mart is just frauding people that will get cashback by card transaction but the cashier does no know to do transaction via card properly
