Poor service

Vumatel has handed me over to a technician from Britelink MCT to fix my fibre, I have been waiting since 12h00 for them to come and nothing. They said they came and when they called the phone rang twice and they dropped the line then they left. I have been trying to call them back, I have sent emails and gave alternative numbers but no assistance at all. I have been without internet for almost 24 hours now. This kind of service is truly unprofessional
