Vodacom do not send technicians until guarantee expires

Having been a customer of Vodacom since the early 1990's I have to say I have decided to move away. I took a Fibre contract and within 3 months started complaining about the service dropping. It took numerous complaints over many months before in January a consultant looked at the history and escalated the complaint. Vodacom came today to say the router is faulty but just out of warranty but they cannot assist unless I sign a new contract too get a new router. The fact that I have complained for months does not matter and the fact that they should have sent out a technician months ago does not matter. They refuse to help unless I enter a new contract. Well Goodbye Vodacom
