Very high contribitions for 2022 ! 🤢

Good day . Iam now a member of sizwe medical aid .but with sadness. I saw that they joint with Hosmed . I went to next year 2022 contribitions And i was shocked too see from R1430 to R1745 .why was i as a customer not notified that the contributions shooting up so freakin high for next year . Then i whould have rather joint another medical aid .i only got email last week sended proof of income email back saying its been updated but witj no amout to say how much . If this medical aid gets so ecpensive i can rather go back to discovery .
