FON Modem not working - still waiting for feedbank

Mweb sent me one of their new FON modems in July 2014. I was told that it is a free modem as long as I use it. If I use another modem then Mweb will expect payment for the FON modem. So I have been using the FON modem since. <br> <br> Two weeks ago the modem stopped working. All the lights are stable, however the internet light does not come on. So I have had to go back to my previous Netgear modem. <br> <br> I called Mweb on the 2/2/2015 and spoke to Imraan Forbes. I wanted to find out what guarantee the FON modem has because I have not even had it for a year. Imraan then did a whole bunch of tests with me on the phone to see if he could possibly pick up what was wrong with the modem. After half an hour he could not figure out what the problem was and so issued me with a reference number and told me someone will get back to me: Client reference number: ***.<br> <br> It is now the 11th of February and no one from Mweb has made contact with me.<br> I want to know if Mweb will be replacing this modem or fixing it? It should still be under guarantee as it is not even a year old yet.<br>
