Unprofessional customer service

Helo Peter..I had the worst experience at Edgar's Mall of the south,I went to make a payment and the cashier said I should swipe my depot card and than swipe my Edgar's account card than I did so,he than showed me that the system is showing the money is not reflecting.He said I must try it again,but than I showed him the SMS on my cellphone that the money went off my bank account,so he said it will go back in my account and that I should swipe my bank card again and than my Edgar's card. I did it again and the money went off my bank account again and I showed him the SMS that I received,he than said he doesn't know what is going on because it's still not showing on his system I than requested a slip from him he than said there is no slip.i requested to speak to the manager.The manager come we explained to him what happened he than said he is going to call the other manager because he also don't know what is wrong,the next manager came and also checked so she said she also can't help she's going to call the store manager and he also came and he said he can't do anything it's the system so I refused to leave the store he than said I should speak to my bank I then went to the bank they couldn't help the store must reverse the money.i went back to the store and the store manager said I'm harassing him his going to call the security for me as I explained to him that was my last money and I need it to get home he than called the security to escort me out.i went back to the bank they reversed the money but the next day Edgar's took the money back out of my account ever since I've been going to different Edgar's stores to get an answer but no one can help me I've been sending bank statement to show the proof of payment but haven't received no reply and I've been a VIP customer for so many years but this is the treatment I get for being a loyal customer.Edgar's is sending me messages that I didn't pay my account and I really run out of options please help me please.
