Non Delivery of Service

I called discovery on Tuesday last week and spoke to Larisa regarding a dependant that was removed from my medical aid without my permission. She admitted that the error was on their side and promised to get a billing consultant to call me the following day. Needless to say, no call was received. Today, I called at around 10:45 and spoke to Evan who promised the same thing. I refused to accept this promise of his as discovery hasn't delivered on their promises in the passed. He mentioned that he called the billing consultant but could not get through. I asked for the contact details of the billing consultant responsible, and he then just kept quiet, but I could hear him typing in the background. He pretended not to hear me on the phone until I eventually hung up. My 5 month old baby is not covered by my medical aid and discovery couldn't be bothered. They just full of empty promises.
