Bad service

I have been with Sizwe for the last 17 years. For the last year more so the last 5 months its a battle to get hold of someone to assist or call back or respond to e mail. They change plans without notification then on admission to hospital you hear of co payments. They suspend your account when there is a dispute on account. After how many phone calls and e mails before and after they suspend membership they cant give straight answers or assist. You pay so much for a bad service
