No Response to a Lodge Complaint

18th September received my statement just to find my normal bill almost doubled. I immediately went to Customer Care Green Acres to lodge a complaint. Got a reference number and was told that I would receive feedback within 48 hours. Up to now nothing!! I plan and managed my two data contracts. I was furious to notice that I was billed an extra R827 on my 2 + 2Gb contract. I use my Top-up contract for extra data bundles when it is needed which is way cheaper than the out of bundle rip-off rates.<br> I want my account rectified ASAP!
