NHBRC doesnt care about small business

I contacted them end of April 2018 to renew my building certificate. I was asked to email all the supporting documents which i did. They where supposed to email me a invoice to pay which they never did. I emailed the consultant on numerous occasions and still no response. I called 21 May 2018 and the consultant said she would check on Mohammed and get back to me the same day and she never. Today when i called in they keep on putting me thru to everyone and all you get is mailbox is full. When i eventually spoke to Mohammed now he says 1. His busy 2. I must wait 3. He must check up 4. Renewals are dealt with by a outside company but no one ever conveyed that to us Also now is there penalties involved for late renewal yet it wasn't my fault... Why is there one person doing this for the entire Western Cape region yet they collecting so much money. I think Stefan Jansen whose in charge needs to re-look this as well as the behavior of his staff towards clients!
