Dare not be old and apply for a medical aid!!

Over a month ago, on the 26 September I app**** for a medical aid for my mother as my stepdad passed away and my mom was now living with us. First of all trying to make contact with them and talk to a living person was almost impossible. They gave me the run around on email and the fact that me and my husband was members for over 20 yrs didn't count. After almost four weeks of inefficiency I appointed a broker from Curemed. Well what a joke, he asked for a letter to appoint him as our broker, which was done immediately, Only to be told after two weeks that he cannot represent us until Discovery has given her a membership number. Well how on earth can we get representation if we are asking for assistance in getting her a membership in the first place. They keep on asking about more information regarding two procedures my mom had 48 yrs ago, which was sorted and never had issues with since then!!! And the doctors did these procedures has passed on! We disclosed all her information truthfully but have been given the run around for over six weeks. Apparently the excuse made by the broker was that the computerized system at Discovery will automatically flag this and has to be overridden by a manager in order for this to be resolved. WELL AFTER TWO AFFIDAVITS from my mom declaring that she had no further issues with a removed thyriod and a removed kidney stone (48yrs ago), sent to the broker and then onto Discovery, no avail!!! I had once again a call asking for the same affidavits that already has been passed on. HEEEEEEELLLLLLLPPPPP! is their anybody that actually make sense at Discovery or is this the ploy to give you the run around so that they can get out of their obligation to provide my mother with a medical aid?
