October Old Mutual complaint

about a month ago i received a phone call from a Brandon indicating that my mother needs to pay the outstanding monies due to her employer not advising her about the payment process after she has gone onto pension. after about 30years of paying Old Mutual i cannot see that my mother looses all her money due to her employer not doing their job. how can i get hold of an ombudsman in the Western Cape or let him rather contact me on ********** 083
