UNACCEPTABLE BEHAVIOUR!!!

I received a call from MBD today, the agent that assisted me was Joy Makgamosi...NO telephone etiquette, no customer service service. I do not know how she got the job but when speaking to a customer key area should be customer service. I advised her I can pay R100 a month then I said email or sms the banking details in which case she said I did SMS it to you...If I am talking to you I cannot check an SMS all you say is " You will receive it soon" then the conversation came about me requesting my contact nr be removed as you harassed me daily everyday you phone me I asked that you phone after 4 in the past which u never did. Anyway wont Mrs Joy advise if u pay your debt we wont phone REALLY NOW DOES SHE UNDERSTAND PEOPLE CIRCUMSTANCES TO BE SO STROPPY...I asked her to remove my work number GET IT I CANNOT ANSWER PERSONAL CALLS AT WORK...I asked her for proof that my nr will be removed she tells me NO WHERE DO YOU WORK WELL IF YOU HAVE MY NR THEN CLEARLY AND I GAVE THE NR TO THEM WHAT THE HECK I NEVER DID SEND ME PROOF THAT I SAID SO!! I would also like an apology from Joy for the manner in which she spoke!
