Rude operator and very unprofessional service

I phoned the Discover Credit Card Division on numerous occasions and was sent from pillar to post. I phoned them again this morning. Unfortunately I did not get the operators name, because they mumble when they answer. I asked if I am at the correct division to apply for a Discovery Credit Card . She said yes, I explained my request, she told me I need to go to a FNB branch to apply for one. I asked her way and she put the phone down in my ear!!!! Very rude and unprofessional. If that is how they conduct business with new clients is it worth obtaining a Discovery Credit Card????
