bad customer service and forcing of privacy

Good day,

I am very upset with a phone call received where private and confidential information was basically forced out of me and in the process was also demanded to make arrangements that i as the client advised don't want to commit myself to and wont be able to keep to my promise. Couple of minutes later i received the following :

Good day Maggie,

Dispute numerous counts of trying to get hold of you this is the last resort of trying to get hold of you, I called you and claimed to be unemployed and we have records of your all your employment including all the loan that you have been taking. So arrange debit order payment with us to avoid legal action.

Kind regards Musa Mlangeni Credit Controller In which i believe that is also my privacy and i did not recall advising anyone that i am unemployed.

NB: please if this is the kind of service delivery the clients receive i am very disappointed

Regards MK
