JUST come back later

I went to pay my account that i have with the tfg group, when i greeted the lady (Pinky) there was NO response... i gave her my card and said i would like to pay my account, she asked me how much and i told her. My card then for some reason declined which seems to have irritated Pinky, i tried the card again and the same thing happened. That is when she threw my card onto the counter towards me and said JUST come back later.. although it has been 3 weeks i have decided to come to hello peter after another problem(1 of many) today. This is the reason that i will be closing my account and supporting them no more.
