Being Called a ***** by a store manager

04/05/2015 walked in the store to purchase an item according to their machine payment did not go through while my bank has notified me that cash has been debited in my account. I've stated to her that it's not the first time this has happened and funds were not reversed till date .I have to go to the bank for statement and produce statement has proof what about bank charges fro statement. I was told that it is not her fault as much as she did not call me in to buy I should not make my problem hers. If the machine state that payment was not successful meaning that it is not successful there is nothing else she can do and she has important things to do. She didn't not treat my query with urgent and professionalism I asked for her name gave me attitude and walked away. Kept on shouting at me saying that just because we customers we think that the world revolves around us...just because I don't understand what she's saying it is not her problem and theres nothing she can do I should go and enquire with my bank as to where the money has went cause as Mr P they have not received any payment from my side. I asked her to give me a solution that will benefit me as a customer.
