Vodacom delay replacing router till guarantee expires so for your cost

I complained monthly about issues with my router and all Vodacom did was reset the router online and then would tell me to turn router on and off. My first call after the guarantee expired was the first time Vodacom decided it required a technician to investigate. Within 3 minutes of the technician arriving he said the router is faulty and needs to be replaced. Because the guarantee has expired they now want me to pay for a new router or take out a new contract which gives a new router. This is really a ****, I paid for over a year for a problem service and there is proof of the issues being long term but Vodacom transfers responsibility. The technicians boss I think his name was jonothan promised to call me back, I have not heard a word, Vodacom’s initial response on Hellopeter said a consultant would call me. I am still waiting for that call. Has Vodacom get so many customers that they do not care about retaining clients. Goodbye Vodacom and as my cell contact comes to an end I will also say farewell
