Trying to cancell my account after 4 months

Hi called the call centre - got cut off after 12 minutes of explaining the problem, second call another person who then said I must call the Cape Town office not JHB. Third call person put me on hold and never returned. 4th Call Nkele Sobe - each prior call with a security check and verification - asked to be put through to accounts - put on hold for 3 minutes - I terminated the call - they have my contact info - no bother of a reply.
