Absolutely revolting service/Nightmare to get a Paid up letter

So you guys only listen to customers when you want their banking details? Since 27/04/2018 i have been waiting for a paid up letter. Everytime I call I get told the same **** story over and over again. If the admin department has a backlog how is that my problem? And what kind of a backlog lasts for more than a month? You collected R3971.94 from my account why do you only pay Foschini R3175.66? Who must pay this R793.91 that is still outstanding???? I told the consultant that made the arrangement i want to settle the account in full. I have been wondering why is it such a problem to get the paid up letter. Now i know why...you kept some of the money for yourselves. Why did you not charge me _I would have paid you instead of lying to me. I have sent emails to the admin team and to Wendy. No one replies. I tell you_I will cancel my Foschini and Homechoice account because they are associated with and you are ******. Who must die so that I get a paid up letter?????????????????????????
