Not happy customer

I have two weeks trying to top up my ticket. If they not off line, the machines have not being working, at milpark was told the person is at lunch. Today finally I am able to top up I have my card and my mother's card. Was told they could not top up two cards at Thokoza park only one card at the time. Tried to explain one is mine and the other is my mother's but it faller into deaf ears. I didn't want to make a sin but I sincerely believe the is no logic in this. Service level is non existing. I was just not happy after two weeks of attempting to top up my card
