Despicable Bankmed!!!

I recently joined Bankmed. A month after I joined the medical aid I added my son as a beneficiary, or so I thought. I filled in all the necessary documents and emailed them the necessary supporting documentation i.e. birth certificate, affidavit, etc. I was then told that he would start benefiting from December 2015. A couple of weeks later the medical aid card arrived with my son added as a beneficiary. I then received a new medical card as Bankmed was now being administered by Discovery, to my shock and surprise my son was not on the card as a beneficiary. I called Bankmed on 5 Feb 2016 to ask what was happening to which I was apologised to and was assured that he would be added in the next 2-3 days. Yesterday on 19 Feb 2016 I called Bankmed again to find out if he had been finally added, my call was transferred 3 times, I was kept on hold for over 5 minutes after which I was hung up on without getting answers. I called for the 2nd time and again to my shock and bitter surprise, I was told that he had still not been added onto the medical aid. I'm angry, disappointed and hurt by the disgusting service I've received from Bankmed.
