DSTV Multichoice - Very Poor Service

My name is Amu (ID # ***), so i decided to buy another decoder to serve as my second extra view on Sunday. Since Sunday i have spent atleast 2 hours daily with the call centre agents to connect and link this to my primary decoder. Ofcourse they managed to link it twice and overbilled me but i cannot watch any channels. On Tuesday they told me my installation is faulty that i should get an installer to come have a look at the cabling, Wednesday i had the installer at the house who charged me a call out fee since there was nothing wrong with the cables. Wednesday i was told to take the decoders to the Randburg multichoice i did that on Thursday morning. One decoder (new) worked and the other (old) which always worked was all of a sudden no longer working and was told to buy another one which i refused. Came home and plugged them, they both worked for like 15 min and then stopped. To this date, i had call centre agents promising to be working on it and that once errors are cleared they would phone me back, some would simple just put me on hold for over 30 minutes. We can only watch Tv from the primary decoder and channel 100 from the 2 extra view and yet my bill is over R800 which no one can explain to me how i can move from R629 to that amount after adding an additional extra view which costs R100. The one call centre agent said to me the additional decoder was linked twice and or maybe my account is in arrears which is impossible since i pay via the whatsapp instant EFT full balance everytime.

Last night i even tried clearing the errors via whatsapp and i was very surprised as i could not recognise the linked decoders, the serial number don't match any of the extra decoders i have in the house.

Oh whenever i phone the call centre i'm told of the slowness if the system which now rather costing me my time, airtime and ofcourse bill that i guess i'll have to pay end of the month for services not rendered.

This has gone beyond me being frustrated and woukd like multichoice to let me know if they are able to help me or so i can cancel their services and if they will pro-rate me for the week that i'm not able to watch their channels.
