Work from home agents treat customers terribly

I just received the worst customer service from one of your call Centre agents in the loan department. She absolutely refused to help me before even getting any of my details. She was rude and kept on telling I must just wait. When I asked her name she refused to give it to me. When I asked to speak to a supervisor she said there is none because she works remotely. She talked over me the entire time refusing to even listen to me. And when I asked her if she is talking to me like that because no one is around to hear her she hung up on me. I would like for you to listen to that call and take note of how your employees at home are treating your customers. I would like feedback on this matter. You really need to investigate this agent. I can't imagine the number of people she has treated so badly.

All I want is for my loan to be paid out. And it's not fair that I do everything you ask and get treated this way.
