Appalling customer service

Please can someone assist me as a matter of urgency. I opened my account on 30 March at the Woodlands branch. On the given day there was a systems issue and we were not able to load the app. The consultant advised me to give it a few days and then try again. On 7 April I went back to the branch as the app still did not want to register my details. It kept on advising to go into the branch. A gentleman by the name of Suvir tried for more than an hour to resolve the issue, eventually referring the matter to a support specialist. ***. I was promised a call back within 7 working days. On 13 April I called into the call centre and spoke to a lovely gent who advised me he can see that the matter is being attended to. Again confirming that I will receive a call within 7 working days from the date the matter was escalated. Since 13 April I have tried numerous times to load and register on the app. It gets to a point where it request me to wait for an sms to be sent to my cell number, where after it then advise that there is a problem

19 April I called into the call centre, and I must say that the lady that I dealt with has no customer service skills. All she advised me that if the app does not work I must register for internet banking, this after I advised her that I do not want to. Instead of trying to resolve the matter, she only advised that she can get a team manager, who will also not be able to assist or I can contact the complaints department. And logged a complaint with a promise of a 24h TAT. Today is 26 April and still no call from anyone from Capitec. It is 27 working days later and still I have not received any feedback or response. PLEASE can someone who knows what they are doing assist to have this resolved.
