Exstreme poor client support

I have two accounts with quite a few services at Axxess. An new MTN sim keeps on blocking, I tried several times to unblock but 20 minutes later its blocked again. I concider moving away to another service provider. I asked several time Agnes at reception to get hold of someone senior that can help but no one calls me back even after many emails and tickets that I have logged. Just a no care support ****ion from Axxess.
