No LTE signal although I've been paying a fortune

I entered an LTE contract with Telkom in November, but I have not had signal since I bought it. I've been paying a fortune in monthly fees, and raised the matter with them when I returned from holiday in January. I've been trying to resolve the matter with them since then, to no avail. 2 technicians have c ome to check my signal, both confirming that I do not have signal, which I already knew to begin with. They are yet to propose a solution, but hare happy to keep taking my monthly fee. <br> <br> The last straw was this morning when I spoke to an obnoxious call centre agent, Sibahle, who was rude and aggressive and no help at all. When I asked to speak to her supervisor, she put me on hold until I eventually hung up. <br> <br> Please, Telkom, either fix my signal or cancel my contract? Either way I would like a refund for the months that I have been paying for despite having no signal.
