very very poor service

I called in today about 5mins ago to the call centre. I asked for a settlement letter because I wanted to pay offthe aaccount. I got a very rude woman. She was even making fun of my accent. This is not the 1st time I 've been treated so badly by these people, if you check my previous 4 calls with these people, you will see how unprofessional these people are. I don't know how this company train their agents. I wish Wesbank could take their business away from these people. I called in on my own being a responsible client, but they made me regret why I called. I ask for their banking details last week as well , up to now I have not received them. Can somebody do something about these people. They also want to charge me for collection, yet I called in my self, no one called me. I am very angry and disappointed with these people.
