ICASA/ SAPO

I've had a few issues with the SAPO and after not hearing anything from the Post office, I took my complaint to ICASA. After emailing back and forth ICASA still has not resolved the issue and now ICASA are not replying. I actually can't believe the regulatory authority responsible for the public safety concerning the SAPO is ICASA. This organization doesn't mean or do anything. I would take this matter to the police, although I fear even less would be done through them. What's the point of having all these regulatory bodies, when they can't do anything. Where is the complaints department for ICASA?
