DSTV MULTCHOICE

to whom it may concern RE: customer number: ***4, I received a message on the 7th of October informing me that my account is overdue with R1800.55 I used the WhatsApp system as well and the amount went down to R1614.99 how that happened only multichoice knows. I then called the call centre and spoke to a lady by the name of Babongile she advised me that the amount over due is R769.00. so now where on earth do you guys get 3 different amounts on one account. I have tried to make arrangements to pay the R1614.99 amount off and they just don't grant any arrangements to their clients. this is a month to month payment where do I get arrears on this account!??
