I had a loan with capitec bank. I requested on 2/4/15 for a settlement amout almost R25000 I paid the amount on 11/4/15.Proof of payment was emailed and faxed after a very long struggle I got confirmation proof and payment received its in the allocations dept.Yet today there is still a balance reflection on my paid up account when I phone(Elista Littenaar ***) for a paid up letter I'm being directed from 1 person to another I email no response so what must u do now!!I'm fed up The brances doesn't want to help me that dept doesn't work on weekends and they must correct the balance showing from headoffice side????
