Discover claims worst service and turn around times

I have just come across the worst service ever. After multiple tries for assistance , numerous calls and emails. I can list the names of all the consultants I spoke to. But the worst is when management cannot respond or read a email. A manager replies with a rejection letter that was sent to the wrong email address and answers no other question. Nicky Morake, Lindokuhle Ngqulungo , Ntekane ,Kgoasi ....none of you could pick up your phone and speak to me as a client, despite the emails and phone calls. My request is simple , send me a copy of the sales call, its been months of no feedback. Your service has been horrible.
