PATHETIC BILLING

I recently purchased two DSTV Explora Decoders from On Air TV on a 24 month payment agreement. However, I want to settle the total amount owed. I have been trying to engage with this company both by e-mail and telephonically, to no avail. E-mails are not responded to and if so - I am informed that their systems are down. Trying to contact them telephonically is also a nightmare. If successful, they just inform that the systems are down and they cannot assist. Their systems have now been "down" for two months. No reference number is provided when communicating and thus no way to trace the inquiry.
