bad service

I have been struggling now for more than a month to sort out my medical aid with discovery. According to discovery my medical aid has been suspended because of non payment but I have a debit order with discovery so how is this possible? I have contacted discovery numerous times to sort out my account and each time you speak to someone else. I sent a mail last week with all the documents to show that my payments is up to date to a mail address provided by the call centre once again and I have not had any response what so ever. I have 3 kids one being a new born baby and if something were to happen I will hold discovery responsible for it as now I have no medical aid. I need this sorted out asap.
