RUDE AGENTS

I received a call from home choice today as I do on a daily basis a couple of times a day. This is EXTREMELY ANNOYING seeing as i have a job to tend to. The lady on the phone called to remind me that i owe them R95 and wants to know when i will pay it. I told her please do not call me im at work. She proceeds to tell me that my account is outstanding while its not yet anywhere close to the end of the month. I hang up and she calls back. I yelled at her telling her to stop calling me. She had the nerve to threaten me and tell me that she will keep calling until i choose to listen to her. I do not appreciate her approach because i am a very loyal home choice customer. If u keep calling at work ill keep hanging up. Dont remind me of an outstanding R95 when iv spent thousands at home choice. Please teach your agents how to treat customers well. After all it is what they get paid for
