Useless call centre!! owing me refund still!

I have still yet to hear back from DSTV after numerous calls i have made regarding the cancellation of the Explora due to misguided information when i bought it and the same content on over and over. eventually somebody came to collect the decoder but still no refund for the month they charged me for after assuring me once in there possession i will be refunded. i had phone call after phone call with totally unrelated stuff after the decoder was sent back such as do i want lighting protection on my decoder i sent it back i said! then how was the delivery of my new decoder am i enjoying it? i sent it back again i said! each time explaining the same story i explained months ago and they assured me somebody will contact me its not there department. i am still waiting to hear back from DSTV...... why would i bother to reconnect my current PVR or any time in the near future with this service or lack there of?
