TV Licence not in arrears

Good day, I am being harassed at my place of employment by your staff for a TV licence THAT IS NOT IN ARREARS. Also, it is impossible to tell your rude and snotty staff this as they reply with \don't you come with your stories I will come to your work and write you up". Please ensure that you fami****ise yourself with the code of conduct your 'brave' call centre agents should adhere to. My work calls are being recorded and you are not allowed to threaten me at my place of employment when I tell you the licence is paid to date and was never in arrears since I bought the TV in 2013!!! One more threat at my work and I WILL REPORT YOU! From now on you will communicate with me in writing so cover both myself and see if your call centre agents are still so 'brave' to threaten and harrass on paper as they are via telephone. """
