Bad Service

I send an email to Capitec Bank Client Services and the Dept Review department with regards to a paid up letter for my loans, which was send to me. I was in correspondence with Kim Erasmus and Megan Groenewald. The problem is that I overpaid on both of my loans and provided them with proof and still no feedback when I will received my refund. I think the service is bad because I have been sending numerous emails and still no reply.
