Discovery information is very poor and inaccurate

I have been in contact with Discovery for several months. I am trying to sort out self payment gap issues. Every time I request information, the SPG is different. It was confirmed closed and when I tried to use a service, I needed to pay. Discovery, over the phone, says its their mistake, but then refuses to rectify. Also, a different service consultant answers each time, so they have no context, and it is impossible to speak to a manager who can resolve issues. Very poor from a very expensive provider. They also give incorrect information on benefits, and customer has no recourse. Good luck to Discovery Bank.
