MBD NO SERVICE AT ALL

I had an account with Homechoice ref ********** 83 which was handed over to MBD i paid the full amount that im owing it was last year November on the 30th. I called homechoice and they confirm that i need to speak to mbd since my account was handed over to them. When i call MBD they transfere me from pillar to post since last year requesting PAID UP Letter no one is willing to assist. Their service is pathetic and its easy for them to get hold of clients but its difficult for us clients to be assisted. I spoke to Marinda, Phumza Foloti and Angie team leader but with no successe to get my paid up letter and i want it to be emailed to **********
