Poor Service from Vumatel and Webafrica!

I have fiber with Vumatel through Webafrica and recently had an issue with a loss in internet connection twice in 3 weeks. I was advised by Webafrica that the only way to sort this issue out would be to rewire the fiber. On Tuesday the Vuma technician came through unanounced at 8:30 when the appointment was for 10am. The fiber was rewired and I was informed by the technician that another technician will come through during the course of the day to splice the cable which was not done. I tried all the techs numbers with no joy as none of my calls were answered. On Wednesday morning the technicians rocked up again unannounced and advised me that they are not sure where the box was to find the connection and will be back later when their head office lets them know where the box is. Nothing happened and I am still without an internet connection. Webafrica is absolutely useless as they can not give me a TAT or a contact number for any manager that can assist. I have contact Webafrica on WhatsApp and get generic answers. CAN SOMEBODY CONTACT ME AND GIVE ME SOME WAY FORWARD. THE SERVICE IS SO POOR. I GET MORE SERVICE FROM A VENDING MACHINE!!!!!!
