3 months later account still not corrected.

in August Multichoice delivered a Explora and we had it connected and all was well but nobody ever called us to activated the payment plan,then December another Explora arrives and they start billing us for 2 subscriptions after calling in 14 times to multichoice they came and collected the 2nd decoder but they still keep billing us. another 6 phone calls later they keep telling us they will reverse the charges and someone will contact us, well the decoder is gone , we are still paying every month for one subscription but the second subscription still keeps going up , we had an over payment of R1164-00 which I was told to transfer into the payment plan which I did and kept paying R850-00 per month. the main subscription is now in arrears and the payment plan is sitting R1660 in arrears . where is my R1164 gone and why am I still been charged for 2 Subscriptions as they have got the Explora back over a month ago and then I was disconnected and they admitted there mistake but won't reve**** the re connection fee.<br> <br> i am at the end of my rope with DSTV.
