Rude call centre staff

I contacted your call centre at 15:46 today because we wanted to confirm what the debit order on our bank account was as we could not remember. All I wanted to know was what company it was and for what for. Not all the extra information and services. The call centre lady was so rude and disgustingly abrupt with me raised her voice and accused me of not listening to her or understanding her in such a horrible tone as if I was a 2 year old. I told her I was not 2 years old and to get stuffed because of the way she was treating me over the phone. This treatment is unacceptable by your staff when all i wanted was to verify the debit order details, nothing more. I trust you will be able to trace this call and deal with your rude staff member.
