Vodacom Bad Service Delivery

I app**** for Vodacom home wifi fibre and received a reference number for approval and address fibre availability confirmation. I followed up 2 days later with Vodacom fibre and was informed that there was no appointment for installation. I made an appointment personally. When the technician arrived, I was informed me that there is no fibre at my address and that I should consult with my neighbors 3 houses down as a trench needs to be dug from their houses to mine. I don't believe that this is my responsibility as home fibre for my address was confirmed before I committed to the contract. I urgently need the issue to be resolved or an alternative wifi connection arranged.
