Bad Customer Experience

I just want to report bad service I received from a consultant at Home Choice. As per NCA, companies are not allowed to call clients after working hours, however I received a call at 19:13 on the 17/04/2018, from a consultant at home choice who was telling me about an outstanding amount on my account. Never have I opted to be called after hours and on top of that, she did not ask permission to speak she just asked me to confirm date of birth, which I did. I told her that I will settle that account. she the proceeded to tell me that after settling I must call customer service o close my account, I wondered why should I do that because I will still use this account. I asked her what is the impact if I leave the account with a zero balance, she said I will incur charges, I asked how because I wont be owing anything. I asked her to calculate how will I incur interest charge if he balance zero, she could not answer my question, she was busy telling me to speak to CS. When i was speaking she was placing me on mute and came back to say 'Dudu, I don't understand what you are saying". I repeated myself 3 times I think. She was very rude. I didn't appreciate the tone of her voice and the fact that she is calling me at the time that is no convenient. As the company says, 'Calls are recorded for "Quality" purpose', I request this call to be listened and I need a copy as well as I need to refer the matter to the Ombudsman.

Thank you
