Bad attitude Not willing to listenArrogant

I have been a client of African Bank for at least 10 Years. I have recently had to make the difficult decision of placing myself under debt review. Well trying to explain this to the many consultants that now call me is impossible. They refuse to accept that as a answer, swear to me over phone. When I ask for a supervisor they drop the call and also refuse to let me know their name because they know they have a attitude problem. If you do not want to take note of what I am saying and get details needed then rather not call me again. Same person has called 6 times in two days. Hope someone in the african bank group can take this matter further, How can you have people working for your company that have no idea at all as to how to treat a client. Pathetic.
