Very rude service from MFC

I received a call from MFC today 10/02/2023 at around 16:03 and an extremely rude lady was with me on the phone.

I asked for her supervisor/manager and she blatantly refuse to put me through to her manager.

I told her she can call me back when she knows how to address customers and she carried on being rude.

Can I please request that MFC Collection department manager get in contact with me to address the matter.
