Useless Service

My mom is an 88 year old who gets her pension from Liberty. Her medical aid contribution is deducted before she gets paid. I've noticed that Liberty hasnt amended her medical premium payment when the premiums went up. I have literally been on the phone ***) AND email (***) for TWO DAYS and have not been able to speak with ONE SINGLE person that can assist me. What do I need to do to get this sorted? This is pathetic. How is a 88 year old supposed to deal with this kind of service.
