Really bad customer service experience

Tell my why could Capitec not help it their own sim card issue I am experience. Called in 7 times since this morning trying to get a resolution. Was told to swap dim cards, check my network options...or put the cats in someone else phone yoh etc after following those steps by a lady called Kele who knew what she was doing. on my 6th call back to avise that my issue is still not resolved I asked for the same previous agent. And the other agent said there is a question I did not answer correctly for validation why not ask other security questions. Now I can only call aback after 24 hours they cant assist on call any more. Now I have to go the branch. Then why did I waste my time calling in. I have Data on this sim now which I cannot use it
