Breach of NCA act and dishonesty to clients

I have a RAF with the company since 2013. Monday I thought to ask for a statement on my account. Petrus Folkus then emailed me the 6 month statement. I then rep**** via email asking my questions, wanting clarity on the payments and the debits/service fees and the growth on my RAF. I even added my own calculations to support my questions. Till now - 3 days later and Petrus is all quiet. I even called the call center to which I was rudely advised "all the service fees are clearly marked on your statement and you should speak to Petrus". No, all the service fees does not reflect on the statement bc from what I pay and the service fees I able to see - there is still a difference of R2500 over the past 6 months which is just nowhere to be listed. According to the National Credit Act I am entitled to know all the service fees ans commission charged. So either get Petrus to contact me or someone that actually takes pride in their work to contact me and explain this discrepancy or I will log a complaint to the national financial board and ombudsman. I want to understand why the heck have I paid almost R4000 over 6 months, my policy only grew with R1300 but there is still a R2500 missing.
