Capitec bank not what it claims to be

I've been with captec bank for 7+ years and i have been nothing but a goos loyal customer to them. For them to breach a contract and not go to extra lengths to rectify their mistake is truly disappointing. I spoke to several consultants and sent all the relevant documents to still not be assisted professionally. Instead I've been abused. I cannot believe that this is the same back that claims to be simple and sufficient, that has done nothing but go against an agreement between myself and them. When my contract clearly stipulates the terms and conditions. Yet somehow it's okay for capitec to go against those terms whenever it suits them. I'm so disgusted at their service and truly appalled by their treatment.
