Changes made to policy without informing me

Both Santam and my broker Hennie Pretorius (Elorus Bleustar) failed to inform me of a change made to my policy. The last policy schedule I received indicate my excess for a MVA claim to be R2500. Upon lodging a claim last week I was informed that the excess has changed to R3500. I queried this with Sanlam and they referred me to my broker Hennie Pretorius, who CLAIMS to have POSTED me the notification of the change in August 2014. Surely any sane person will not rely on the SA Postal service? Everybody knows that the post office has been on strike for an extended period of time? My question is why was I not e-mailed the change in policy - the same way I was e-mailed the previously policy? My e-mail address has been the same for almost 15 years, my phone number has been the same for over ten years. So there is absolutely no excuse for both Santam and my broker to have contacted me electronically which would have also served as proof that the communication had been done. I have been in touch with the Insurance Ombudsman to query this and I was informed that the only acceptable PROOF of NOTIFICATION is registered post or e-mail with electronic tracking. Pathetic!
