DSTV Explora error codes

I upgraded to a DSTV explora decoder mid July. Ever since then I've had a constant stream of error codes that can't be cleared online. I've spend hours on the phone, ringing up a massive cellphone bill. Every day the error code is cleared just to have the same thing happen the next day! Now again I have error code 102. I spend 25 minutes on the phone with a CC agent when the line goes dead. She didn't try to phone me back. I phone again and spend 40 minutes on the phone with another agent, and her final response is basically that she has cleared the code and there's nothing more she can do. I have to wait and see if it clears itself. It is utterly ridiculous! I pay the PVR, catchup and box office service but can't use any of it. I can't even pause my TV! I have to pay expensive cellphone bills and my subscription fee but DSTV has no commitment to actually deliver the service I pay for. I demand that someone fix my problems once and for all and want to know if there is a process to have my phone bill reimbursed?
