Vumatel service disappointing

Very disappointing service every day it's the same story just to reconnect my connection. If the technician is coming every day and my query is being escalated to the manger nothing happen. Mind you I have paid for a service that I have not used they also say that they do not reimburse on down time. Let's not forget how it takes them 5 hrs just to respond to a WhatsApp msg. When they do reply it's a different person and you have to explain your story to them again. Since to date I have not had joy from Vuma it's like they dont care. I work from home and not having internet is a huge problem. No one has called me regarding my problem I have asked to cancel my subscription and refund me but they are just not interested. The service is really pathetic and I've really just had it with them. VERY DISAPPOINTING such an embarrasment
