CAPITEC, customer care and service - PATHETIC

I am unable to access my Capitec account since Capitec upgraded their app. I have contacted them numerous times, via online banking, via WA help line, phone, email on 3 occasions and even complained on Hello peter, This has been going on for months now still not sorted. Emails have been responded to saying complaint has been escalated and someone will contact me, no one has ever got back to me. Phoned helpline from Uk, after 35 minutes on phone was told manager will call me, nothing! Review on Hello Peter, no response! I am in UK and all i get told is go into a branch, like really! I can't even get them to close my account and transfer all my funds elsewhere and close my account TO ALL THOSE PEOPLE WANTING TO JOIN CAPITEC, THINK AGAIN, THEY HAVE BECOME JUST LIKE ALL THE OTHER USELESS BANKING INSTITUTIONS IN SA.
