Bonitas medical aid wrongfylky suspended by them.

My sisters medical aid got suspended due to a refund they said they did. We never received the refund. We keep in sending bankstatement and proof of payments to emails and there whatsapp call centre. We even phoned them last week Wednesday. Spend the whole day day from 10 am till 14h30 before they lift the suspension and said all bills are going to be paid while they going to get there finance dept to fix the account, yesterday the account got suspended again, can you believe that we can not speak to there accounts dept anymore. All we get is reference numbers. Whisk we got about 10 reference numbers now and it is still going to take 3 to 10 working days before we will now the out come. Now what is going to happen if my Sister needs a hospital or a doctor urgently in this waiting period. According to the whatsapp chat they confirm that the suspension of the account is lifted. And all medical rated bills will be paid. But now we are setting with unpaid bills. We contacted the again today but they said they cant not do anything. Guess what I got another reference nr and a waiting period of 3 to 10 days. What can we do to get this resolved today. Any one else that can get is results please. Show you help centre are no good good. They must do away with whatsapp is of no use if your account is suspended. They don't even deserve a one star.
