Bonitas - Bad customer service

My daughter, son-in-law and grand son immigrated to the UK earlier this December. My wife and I were on the same medical aid as the kids "Benefit Date: 01/06/2023" Before they left the country they were dealing with Bonitas since early November so that my wife and I remain on the medical aid which my son in-law is paying. After spending HOURS on the phone with the call center (Bonitas) we are still struggling to get this actioned. Every time we phone and explain the issue, they give us a reference number saying to phone back in a few hours to hear the outcome. When phone back, giving the operator the reference number, it can never be traced on their system. If I can advise clients out there looking for medical aid,,,,,,, take cover and rather get a more competent medical company to look after you
