No capacity for further installation???

So my new installation order was placed 06 July and a team came to install 09 July but could not complete due to a blocked duct. After several weeks of me following up and getting nowhere, i finally get informed today 25 July: "Vumatel has informed us that there is no capacity for this install. According to environmental team, there's no infrastructure, the duct capacity is not allowing an additional installation and there's no other way they can put in another duct." So you are telling me that when laying the infrastucture, you never catered for the amount of houses in a street?? Do you expect clients are to remain in the stone ages and not join the first world of fibre? I do not accept this!!! I expect something to be done since many are working from home and require a stable connection. I await your response
