**** service from BONITAS regarding membership contribution

My Son Michael Croukamp has joined the Bonitas Medical aid from the 1st of January 2025 he received a letter to say that his membership is payable in arrears. 1 week ago he received a letter from Bonitas to say he must pay R2996 that will be deducted 1 Feb 2025 because they did not up date his details at their finance offices to make sure that his membership is payable in arrears and that the amount deducted must only be R1498. I phoned this morning to speak to a consultant to sort this out because he is still a minor and I was informed that he must pay the amount double month end and then they will credit him. I explained to them that he only have a available his monthly contribution which is R1498 and that they should fix this by end of business today. they are not very helpfull in sorting this out their service is **** to say the least. the medical aid broker also contacted them several times to sort this out but they are not bothered to sort this out
