Over rated - WRONG deduction

Fedhealth pushes up the medical Aid so high for 2 students and myself. I went from 3600 to 4375 in one month. I cancel duribg Coronoa cancel my medical aid just too expensive. They deduct over approx R5600 after an official informs me a deduction was to take place last obe this mobth. Why the extra 1000 plus. I am mad busibesses just take advantage diribg Covid have we not enough to deal with?
