Router not working - no signal

On 28 May 2015 I received a router from Mondo Telkom. However, there is no signal and I can not use it. I contacted Mondo on the next Friday and the lady assured me it was activated. On the Monday I phoned again and was informed it was not activated. The lady told me she would activate it. Yet, I still had no signal. I was told that Telkom has no towers in White River, the area where I live. <br> I sent Mondo an e-mail on 3 June. Mondo contacted me. I spoke to Sasha. She asked me to put the sim in my cellphone to check if I get signal and to phone her back. I did that, however, when I phoned back, she was busy on a call. She was going to phone back, but never did. I phoned a few times after that and every time she was busy and never phoned back. I sent them another e-mail on 17 November with no response. In the mean time I money is deducted from my account every month for an item I have no use for. The original agreement was that R89 would be deducted from my account, but they now deduct R106 for an item I have NO use for!!!
