Worst service ever from Capotec

Me and my wife took a day off at work to visit Capitec in Hartbee****rt. Our intention was to update the phone details for our two 13 year old kids, and to have the app installed on their phones. Upon arrival, we were told that our kids are not allowed to enter and that they should stay outside the bank. It is quit obvious that no one at Capitec has Kids, or have access to media, or knows anything about child abductions, which incidentally happened at this mall not to long ago. After relaying these concerns to the branch manager, we were no better off. I phoned the client care line, the operator, called Milly, after 17 minutes on the line, she kept us waiting on the line for 9 minutes, while she tried to find corroborating information on their policy which refuses paying clients to enter the bank. After this I had to hung up. Incidentally, on the same day we visited another bank where we do business banking. Our kids were accommodated and even offered accounts, which we declined. My question is, what do we have to do to get service from Capitec. I am 5 minutes away from closing all our accounts, and move to a bank with some savvy!!!!!!!!!!!
