Bad service

Im very disappointed about the service I received from your diepkloof branch...I used my card to make purchases and they were having some system issues which showed on their side that my payment didn't go through I showed them an sms of the purchase I even went into the app to show them i was told I had to wait 72hrs for them to reverse my money so sad part I had to pay using cash cause I really needed food now I'm waiting hoping I'll get back my money within the said time... anyway I don't see myself doing business with them
