Very bad multichoice

I am very disappointed in multichoice,I have been fighting with them since October to assist me with my dstv,now they are telling me that I owe them R1500 when I tell them I've been paying they tell me about credits which they failed to tell me about each time I enquired about the premium I specifically asked how much am I paying every month and each time I call I get a different amount,my debit order is for the 24th of each month I even ask always when Im on the call with them when mt debit order on their system says must it go off.im always told someone will call me I always call them back because no one calls in 48 hours when I call I hate the fact that o have to repeat myself again then they have the ***** to tell me that they don't know but don't refer to someone who does...I have recieved nothing but she service from dstv,I made sure as a client that its my responsibility to make sure my account is up to date but I still don't get any service or assistance and now they want me to pay,they have turned of my viewing its the 23 debit is suppose to go tomorrow I called Friday Saturday Sunday till today no one has called today alone I spoke to 3 different people now I've been put on hold and im still on hold and I've been on the phone for over a hour now and I'm still holding for a so called manager to talk to me as I am typing I I using my work resources and not assisting the clients I need to assist because dstv cannot be competent enough or hire competent people to assist me im going to cancel my subscription and also make a noise about it on all social media platforms this is utter nonsense
