Absa bad client service

Been with Absa since the inception; private bank client and have a home owners policy. My geyser is leaking from the casing, meaning I probably have to replace the geyser. Absa is now wanting this absurd amount of R4000 excess, for a job which is probably not going to cost that much (being small geyser). When I requested an explanation, I was told that I have a amendment on my policy (from many years ago), due to more than usual claims (flooding - not my fault). And if I want to contest this, I have to make a request. So no proactive review of my situation (being a private bank client at Absa never gave me any real benefits and now not even in this case). Extremely ****py, sub standard & unprofessional service from Absa. Maybe time to move on to another insurer (and bank for that matter), who is actually interested in client satisfaction versus milking the client...
