Bad service. Refund must be issued

Bad service. I'm residing in Devland Soweto. Paid full amount of the vuma fibre haven't had a connection for 7days since last week Wednesday and currently I'm working from home. I've lost so much in this 7days not being able to work, i wanted this fibre because I thought it would be helpful to me since I'm working from home. No one answers customer service calls. Take time to respond ,lack of communication and poor service. The sad part as I paid a full amount they will want to deduct again end of the month once I've stayed for full week not working and no internet connection. It's either you fix this connection as soon as possible or you refund us backsince it's not even a contract because also those technicians that come to install have bad manners. They just install and say wait for the password they dont even check how the connection goes so far and even explain how this fibre works. Vumatel must refund us honestly for this poor service it's not our fault that you dont have technicians since we are paying we want connection
