Discovery medical aid inefficentcy

I have been on my own discovery medical aid since I was 18 . It has been 10 years now recently I decided to add my husband as a dependent on my medical aid. Well was this a fight. When speaking to the original consultant all was fine and she told me to send in required documents and it's would be effective from the 1st of that month. 2 days before the first I get a phone call to state my husband cannot be added. I fought with them for 6 weeks as my husband was now sitting without a medical aid as hos previous one had been cancelled. Eventually they said he can be added and they will waver it because it had been the consultants fault. Now finally excited we have a family medical aid. The 1st of June come along our first debit order and once again it's a stuff up. I was debited nearly 3 months of medical aid. In tears I phoned the customer help line whilst on the phone the consultant stated that his medical aid had been effective on mine from the 1st of April that's when I realized again they have made a mistake . I rep**** by saying how could this be possible when my last formal complaint with you guys was lodged in the 2nd may and staying on my membership certificate it says effective from 3rd may . She said she was doing to transfer me to the account department a while goes by and no answer so I asked her why is it taking so long for them to answer and the consultant rep**** saying they don't operate on a Saturday. Shocked as usual I rep**** well why did you transfer me if no one is going to answer. Anyway to end off my never ending problem with discovery the lady advised that she can only send in this information on Monday once again I have not been helped . I am sitting with a negative bank balance because of inefficient service . Discovery has been a constant battle this year and I am sad to see how ineffective they are .
