I did a new installion last month

I did a new installion last month. A week later the line was down because the guys left a piece of line hanging. A call was logged and they came to fix it. A month later the line is down again. Another call has been logged. I am at the verge of canceling. I just don't want to be billed for early cancellation because really how is this my fault? I work from home, now I have to travel to the office because I don't have internet and my life has to come to a stop again because I have to make time and wait for the technician to come. I was on Telkom LTE and I never had such issues. I regret changing to Vumatel
