Unanswered calls

I have tried multiple times to contact the Old mutual call centre. Today I decided to document my holding time: Upon calling number ***, I held for 20:04 minutes and there was no answer. I then tried a different number: ***and held for 14:29 minutes and still no answer. Bearing in mind, I called after 09:00 so one would assume the call centre staff are at work. How are we supposed to get any assistance when the call centre does not answer the call. And, if there are alternative numbers to call, then why are these numbers at the forefront when you go to their website. This is unacceptable! I am going to move my savings!
