Unjust waiting period for a person who has been on discovery medical aid for over 20 years

My parents have been on LA Health (Keycare Plan) underwritten by Discovery Health since 2012. Previous to this they were on Keyhealth for over 18 years.

My mother resigned from work on the 30th June 2022, she contacted Discovery direct before the 30th June 2022. She made sure of this as she did not want a "break" in medical cover.

My dad has now tried to join the same plan through his work with no break in membership and now Discovery have now said that he will have a "3 Month waiting period". This is UNACCEPTABLE. There has been no break in medical aid, no break in payment and NO CHANGE IN PLANS.

The cover is the exact same. The only difference is that my father will be paying for himself.

There is no reasonable explanation that this waiting period needs to apply.

There is no need to have a waiting period because my dad has been with discovery for over 20 years. It seems that Discovery is trying to take advantage of my elderly father even though our whole family have been loyal clients for over 20 years.

Please can someone contact me so that this can be rectified and this poor review can be corrected and turned around.

I hope that this matter is met with some urgency as right now my father has no cover which is unjustified and dangerous
