Medshield/GEMS is **** medical aid scheme

For the past 2 months have been sending emails and fax to this useless medical aid to change details and beneficiaries, they send and email stating that they will call in 48 hour but they never do, and when you make a followup call they always answer with silly attitude and place you on hold for a very long time after that they tell you they can not find your email or fax and you should resend them the document. Employer (Government) should cancel this useless medical and give employees to choose their own medical aid scheme cause this tender schemes are useless and a waist of our money.
