Vodacom fibre support useless

My old router is giving issues after 6 years, bought my own router because vodacoms routers arent the best and now vodacom is forcing me to use there routers. They are blocking my router. Old router still works and now they have blocked that one as well. Vodacom just keeps on showing me why i should be using them at all. They forcing me to use an outdide technician just to go through the same steps as me to allow my router to work. Now i have to pay for someone to give the same info as me. If this isnt resolved today then im moving to another previder. Not even telkom gives me this much trouble
