Disgusting Service from Capitec

I've been a very loyal client to capitec, and recently my account has been put on hold , for what, I don't know, noticed that when I was trying to swipe with the card, I have been fully transacting on this account for years and I've never came across such, I went to the branch and they just logged a query and they don't even have a number that we can contact these people on, im so irritated at the moment because everything is now stuck. I can't solve my emergency responsibilities.
