Unbelievably pathetic client service

I have been trying for over a month to get a Benefits Statement from this company. The local office referred me to their Pensions dept in Jhb - where you hang on and on hoping that someone eventually comes on the line. After several tries, a consultant promised to send it. Today I called Jhb again with no success in getting to speak to someone. I tried logging a complaint - their complaints email address bounces back undeliverable, their website will not connect and the complaints line cuts off after a few rings. in desperation, I called their Umhlanga office again - onthe first call a lady took all the details and asked me to wait a moment while she transferred me to someone who could help. After 5 min of hanging on I cut the call and called again. This time another lady answered and said she was transferring me to someone - only to listen to recorded messages with options irrelevant to my query. How does one deal with such pathetic client service? Shocking that it comes from a financial services provider who promises to look after your hard earned savings in your best interest.
