dstv, zero service company

I had a problem with my billing and eventually managed to get a reference number INC ***. They promised to get back to me within 24 hours. That was nearly 2 weeks ago. Nothing. Every agent that I speak to has no idea about any reference number and has no idea on how to give me any feedback. I can also not find any phone number to phone. So, if anyone wants a new explora remote , send me your details, I'm finished with dstv
